Description Mark 2007-11-10 16:22:24 UTC
yum-updatesd-helper is banging away at the network and won't allow package manager to run when needed. I have 2 machines and they both are doing this. There are also many posts on the forums about this problem. The yum-updatesd-helper process is out of control. When machines are sitting idle, there is constant network activity from the process and yum can't be used. This affects Fedora 8 installs No steps needed to reproduce
Comment 1 Ville-Pekka Vainio 2007-11-10 17:04:44 UTC
Created attachment 253991 [details] Log of HTTP messages sent by yum-updatesd-helper
Comment 2 Ville-Pekka Vainio 2007-11-10 17:07:34 UTC
I'm seeing this too, it makes using yum almost impossible, since the network and the yum lock are always taken. I've attached some log I made with fireshark, it seems updatesd-helper constantly downloads updates comps-f8.xml here.
Comment 3 Luigi Tarenga 2007-11-10 17:56:44 UTC
i killed the yum-updatesd-helper process and did some experiment. "yum update" works, i was able to install new packages. "yum grouplist" does not work, here the output that seems related to the helper problem: [root@bug1 updates]# yum grouplist Setting up Group Process http://ftp.gui.uva.es/sites/fedora.redhat.com/linux/updates/8/x86_64/repodata/comps-f8.xml: [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')> Trying other mirror. comps-f8.xml 100% |=========================| 1.2 MB 00:13 http://www.jur-linux.org/download/fedora/updates/8/x86_64/repodata/comps-f8.xml: [Errno -1] Metadata file does not match checksum Trying other mirror. comps-f8.xml 100% |=========================| 1.2 MB 00:13 ftp://ftp.uninett.no/pub/linux/Fedora/updates/8/x86_64/repodata/comps-f8.xml: [Errno -1] Metadata file does not match checksum Trying other mirror. .... the process go on with the same error on many mirror (i didn't try them all :))
Comment 4 Mauricio Teixeira 2007-11-10 18:41:59 UTC
+1! I've seen this happen in my desktop with x86_64 version, but not on my laptop with i386 version. Can't tell where does it comes from also, but looking at netstat it seems that updatesd is trying to get repository files from all the mirrors repeately.

have same problem on an i386 fedora8. yum-updatesd does download several hundred MB's until its dead... yum update over console is working fine.

Comment 8 Ken 2007-11-10 20:59:02 UTC
Same problem here. I did a fresh install of Fedora 8 this morning and when I went to use Software Updater, it started retrieving software information. It sat there retrieving software information for 40 minutes and caused 321 MB of download traffic before I killed the process. Using Yum in the terminal works fine.
Comment 9 James Antill 2007-11-10 21:06:17 UTC
> It sat there retrieving software information for 40 minutes and caused 321 MB of download traffic before I killed the process. This is "normal" in that there were/are 100s of MBs of updates for Fed-8 available as of this morning. So as soon as you reboot into Fed-8 yum-updatesd will spawn a yum-updates-helper which will start downloading all of those updates. While it's doing this it takes the yum lock, so you can't run yum/pirut until it's finished. If you "service yum-updatesd stop" that will not kill the yum-updatesd-helper _because_ if yum-updatesd-helper is in the middle of installing the downloaded rpms it can do very bad things to your rpmdb. _If_ you know it's still downloading you can kill yum-updatesd-helper manually, this should let you use yum/pirut fine (at least I've not seen any evidence of a problem, other than slow network). If someone has a bug that isn't explained by the above, please add a comment.

Comment 11 Andre Robatino 2007-11-10 21:16:47 UTC
I first experienced the problem today AFTER I downloaded all the updates about 1.5 hours ago, and rebooted into the new kernel. I noticed that the networking light on my router was just going, and going, and going, and yum wouldn't work because of the lock error. In F7 that would happen for a short time but then stop when yum-updatesd finished checking. This time, there were no new updates, so that's not the explanation. I don't know why it didn't happen after the last time I booted (about 2 days ago).
Comment 12 Ville-Pekka Vainio 2007-11-10 21:36:10 UTC
(In reply to comment #9) > If someone has a bug that isn't explained by the above, please add a comment. This behavior is not explained by available updates. For example in my case I have installed all the available updates with the yum CLI. But if I start yum-updatesd, it will still (apparently) download the repodata files constantly, until I kill yum-updatesd-helper with kill -9.
Comment 13 Andre Robatino 2007-11-10 21:40:35 UTC
To verify that the problem is reproducible, I've just rebooted and logged in again. All updates are applied, including last night's batch, and I'm running the new kernel. In F7, even with a large batch of new updates, it didn't take more than a minute or two for it to finish its hourly check and display the puplet icon. At this point, it's been running about 15 minutes even with no updates (I also have a "yum update" running in a terminal, giving the lock error repeatedly, so will know if it finishes). I will report back if it finishes within an hour or so, or kill it if it's still running by then. I should also mention that the "yum update" I did to download last night's batch of updates finished in normal time, so the server can't be that overloaded.
Comment 14 James Antill 2007-11-10 22:39:20 UTC
Ok, Andre/Ville-Pekka can you tell me what options yum-updatesd-helper is running with? (ps axuwwwwf | fgrep yum-updates) Can you try running the following and pasting the output: /usr/libexec/yum-updatesd-helper --debug <options> ...where <options> are replaced with the options you see from the ps. For instance I'm trying: /usr/libexec/yum-updatesd-helper -c -d --deps --debug ...and while it says there are 6 updates available, it exits almost immediately. Also can you run (and see if anything is different): % rpm -q yum yum-updatesd yum-utils python-urlgrabber python yum(0:3.2.7-1.fc8).noarch yum-updatesd(1:0.7-1.fc8).noarch yum-utils(0:1.1.8-1.fc8).noarch python-urlgrabber(0:3.0.0-3.fc8).noarch python(0:2.5.1-15.fc8).x86_64
Comment 15 Andre Robatino 2007-11-10 22:50:22 UTC
Amazingly enough, my yum finally started up just a few minutes ago, letting me know there are no updates. Running "yum clean metadata" and then "yum update" finishes in less than a minute, but yum-updatesd took about an hour, or about 2 orders of magnitude longer. I can't get yum-updatesd-helper running again without logging out and back in, but the following appeared in /var/log/messages at what is probably the time that yum-updatesd-helper exited: Nov 10 17:39:21 localhost yum-updatesd-helper: error getting update info: 'module' object has no attribute 'GroupError' I haven't changed any defaults. The only customization I've made is installing yum-presto, and the livna-release, dribble-release, and adobe-release packages to enable those repos. [root@localhost ~]# rpm -q yum yum-updatesd yum-utils python-urlgrabber python yum-3.2.7-1.fc8 yum-updatesd-0.7-1.fc8 yum-utils-1.1.8-1.fc8 python-urlgrabber-3.0.0-3.fc8 python-2.5.1-15.fc8 [root@localhost ~]#
Comment 16 Mauricio Teixeira 2007-11-10 23:24:37 UTC
Hey, guys, I found the root cause of the problem. After facing the same problem with yum-updatesd and pirut, I little of network debug with 'wireshark' gave me the directions on what should I be looking for. # yum grouplist Setting up Group Process comps-f8.xml 100% |=========================| 1.2 MB 00:06 http://ftp.nluug.nl/pub/os/Linux/distr/fedora/linux/updates/8/x86_64/repodata/comps-f8.xml: [Errno -1] Metadata file does not match checksum Trying other mirror. comps-f8.xml 100% |=========================| 1.2 MB 00:09 http://ftp.funet.fi/pub/mirrors/fedora.redhat.com/pub/fedora/linux/updates/8/x86_64/repodata/comps-f8.xml: [Errno -1] Metadata file does not match checksum Trying other mirror. (...) And it keeps going until all the mirrors are checked. So, the problem is that the either the file comps-f8.xml is corrupted, or the information of the file in repomd.xml is wrong. I any case, a rebuild of the repodata would be a way to fix.
Comment 17 Andre Robatino 2007-11-10 23:30:48 UTC
In case it helps, yum-updatesd-helper is running again, and I get [andre@localhost ~]$ ps axuwwwwf | fgrep yum-updates root 2272 0.0 0.4 21564 8476 ? SN 16:25 0:00 /usr/bin/python -tt /usr/sbin/yum-updatesd root 3445 4.5 3.9 92472 82176 ?

If not I'll try running /usr/libexec/yum-updatesd-helper --debug --check --dbus when the current instance exits. I'm also currently running "yum update ; date" to verify that the time the lock is freed is the same time the error message appears in /var/log/messages.
Comment 18 Andre Robatino 2007-11-11 01:59:37 UTC
I verified that the error in /var/log/messages appears when yum-updatesd-helper exits. Running the debug command shows nothing new: [root@localhost ~]# /usr/libexec/yum-updatesd-helper --debug --check --dbus Loading "presto" plugin Setting up and reading Presto delta metadata No Presto metadata available for livna No Presto metadata available for adobe-linux-i386 No Presto metadata available for updates No Presto metadata available for dribble No Presto metadata available for fedora Setting up and reading Presto delta metadata No Presto metadata available for livna No Presto metadata available for adobe-linux-i386 No Presto metadata available for updates No Presto metadata available for dribble No Presto metadata available for fedora Check for updates failed: 'module' object has no attribute 'GroupError' [root@localhost ~]# Everything except the last line is printed in the first few seconds, but the last line takes about an hour to print.
Comment 19 James Antill 2007-11-11 05:28:15 UTC
> And it keeps going until all the mirrors are checked. So I'm not seeing anything like this atm. ... that might just mean I've been lucky, or it might be some weird mirrorlist problem. I'll try and check some more tomorrow or monday. But to mitigate this you could pick a mirror from: mirrors.fedoraproject.org/publiclist/Fedora/8/ ... and use that as the baseurl commenting out the mirrorlist. Then even if you're still having problems yum-updatesd et. al. will only download the xml data once (then they'll error out).
Comment 20 Luigi Tarenga 2007-11-11 11:08:47 UTC
hi all, i think it is just a problem of checksum for the comps-f8.xml. why i can say that. i had as all of you, pirut and pup not working. looking at the "yum grouplist" error i see the checksum error so i tryed to "skip" that check. to make so i modifyed /usr/lib/python2.5/site-packages/yum/yumRepo.py (it's a TEMPORARY WORKAROUND DO NOT USE IT ) here the diff: --- yumRepo.py 2007-11-11 11:59:11.000000000 +0100 +++ /usr/lib/python2.5/site-packages/yum/yumRepo.py 2007-11-11 11:59:39.000000000 +0100 @@ -802,10 +802,11 @@ except Errors.RepoError, e: raise URLGrabError(-3, 'Error performing checksum') - if l_csum == r_csum: - return 1 - else: - raise URLGrabError(-1, 'Metadata file does not match checksum') + #if l_csum == r_csum: + # return 1 + #else: + # raise URLGrabError(-1, 'Metadata file does not match checksum') + return 1 as you can see from the diff it skip the checksum check and always return ok (1). now pirut works fine!!! and pup also, it just give this output [root@bug1 ~]# pup Failed to add groups file for repository: updates - comps file is empty/damaged but works. i think the solution is just to correct the checkrum on all mirror. bye bye
Comment 21 Fabio Airoldi 2007-11-11 14:29:15 UTC
I think the problem stays somewhere in the updates repository. Running pirut --repo=updates does not work (the progress bar stops at 100%). It works with any other repository (i tested fedora, livna and adobe-linux-i386). I hope to be helpful.. Bye
Comment 22 James Antill 2007-11-11 15:48:55 UTC
Well I'm seeing it now too, repomd.xml says: <data type="group"> <location href="repodata/comps-f8.xml"/> <checksum type="sha">e4e400aa672481bf1d9e70c008e1c95ee98c0cb7</checksum> <timestamp>1194644692</timestamp> </data> ...(ts = Fri Nov 9 21:44:52 2007 UTC) but my comps-f8.xml is (1194668210) 2007-11-10 04:16 with sha1sum 3a850436d3988e93235903d8a90a5c98f14a4908. I altered the repomd.xml file by hand and that gets past the download check, but the comps file itself is broken, lines 287-289: <name xml:lang="bs">Podrška za arapski</name> </name> <name xml:lang="ko">아랍어 지원</name> ...and line 1331: <name xml:lang="el">Î¥Ï<80>Î¿Ï<83>Ï<84>Î®Ï<81>Î¹Î¾Î· Bhutanese</office.org-langpack-bn</packagereq> ...and that error seems to be repeated a bunch of times. So it's basically unfixable by hand, *sigh*.
Comment 23 James Antill 2007-11-11 16:00:23 UTC
It's worth noting that if you just change the repomd.xml file to contain the "correct" timestamp dna sha1sum pirut/etc. will work for everything that doesn't need the compas data.
Comment 24 Luke Macken 2007-11-11 16:26:28 UTC
The comps-f8.xml/repomd.xml that bodhi mashed matches up correctly. We hit this issue once before, and were hoping that we wouldn't hit it again. Our master mirror may be corrupting things. In the mean time, I kicked off other f8-updates mash. Hopefully this will sync out uncorrupted.
Comment 25 Ron Yorston 2007-11-11 16:47:29 UTC
Getting the comps-f8.xml file fixed would be good, but there's an underlying problem with yum-updatesd-helper that needs to be fixed too. Especially since this sort of corruption has happened before. yum-updatesd-helper should be more intelligent about its use of bandwidth.

Comment 27 Andre Robatino 2007-11-11 18:55:57 UTC
Please change back the name of this bug, and also increase the severity. The misleading name is probably leading to duplicate bug reports. The problem has nothing to do with the volume of updates, since it happens even when all updates are applied.
Comment 28 Joe Christy 2007-11-11 19:01:48 UTC
FWIW firefox, when it tries to open: http://mirror.anl.gov/pub/fedora/linux/updates/8/x86_64/repodata/comps-f8.xml reports: XML Parsing Error: mismatched tag. Expected: </group>.

Comment 29 Joe Christy 2007-11-11 19:03:46 UTC
Is there some compelling reason to mark this as medium severity? The effect of this bug is to render pirut, pup, pupplet, and system-config-packages _unusable_ for _anything_, to any f8 who has the updates repo enabled. Any ETA on when this can be fixed?
Comment 30 Luke Macken 2007-11-11 19:10:02 UTC
I'm seeing a good comps-f8.xml on our mirror, as well as populated on a couple of others. Can someone verify that this is fixed?
Comment 31 Mauricio Teixeira 2007-11-11 20:06:04 UTC
A few mirrors are still out of sync, but at least now it's taking less tries to get the right file. Thanks.

Given that we shouldn't hit this when the repo is in the correct state, I'm not going to rush the update out today and instead going to make sure there's nothing else which needs fixing

It would still be nice for historical purposes at least, so people can look up this bug, if the summary for it was changed to something at least remotely accurate (in particular, it has nothing to do with updates).

Comment 38 James Antill 2007-11-15 14:03:43 UTC
I've just checked: http://download.fedora.redhat.com/pub/fedora/linux/updates/8/x86_64/repodata/ ...and both the sha1sum and xmllint is happy, please note that this sometimes happens a little bit due to mirrors not syncing immediately.
Comment 39 Alexei Podtelezhnikov 2007-11-15 16:23:16 UTC
It was a bad idea to push, pull, and never push back firefox update... some mirrors are still broken because of that, so yum and yum-updatesd keeps stumbling there.
Comment 40 Radek Bíba 2007-11-15 16:38:42 UTC
Okay, it's alright here now as well, where 'it' means the comps file. yum-updatesd-helper (or whatever is responsible for the madness) is still broken, though...
Comment 41 Ville-Pekka Vainio 2007-11-27 15:48:01 UTC
I'm seeing this yet again. Could you please fix yum-updatesd so that it won't constantly download even if the xml files are broken? Also, I think this bug should be reopened until the issue is really fixed.
Comment 42 NILMONI DEB 2007-11-27 16:36:00 UTC
This is getting really annoying. This bug is preventing users from fixing other bugs like https://bugzilla.redhat.com/show_bug.cgi?id=368871#c10 . I tried to update a bug-fixed package from command-line -> $ su -c 'yum --enablerepo=updates-testing update system-config-network' Existing lock /var/run/yum.pid: another copy is running as pid 2996. Another app is currently holding the yum lock; waiting for it to exit... Another app is currently holding the yum lock; waiting for it to exit... Another app is currently holding the yum lock; waiting for it to exit... "ps -ef" shows /usr/libexec/yum-updatesd-helper running in the background. The title of this bug needs changing and this bug really needs fixing.

Comment 44 Ville-Pekka Vainio 2008-01-12 16:01:54 UTC
I'm seeing this yet again. I had one F8 installation that hadn't been used for a while, after starting it yum-updatesd-helper started the download. The system has been up now for 3.5 hours and it's still constantly downloading the comps file. alviss.et.tudelft.nl is the latest mirror it was downloading from, but I guess that specific mirror has nothing to do with this. When will yum-updatesd be fixed so that it won't constantly download the file even if the file is broken?
