urlgrabber errors on usage
Last modified: 2007-11-30 17:11:27 EST
Description of problem: using urlgrabber to get anything generates an error. Version-Release number of selected component (if applicable): Fedora Core 5 with python-urlgrabber-2.9.8-2 How reproducible: every usage Steps to Reproduce: 1. urlgrabber http://download.fedora.redhat.com/pub/fedora/linux/core/5/i386/os/repodata/repomd.xml Actual results: urlgrabber http://download.fedora.redhat.com/pub/fedora/linux/core/5/i386/os/repodata/repomd.xml Traceback (most recent call last): File "/usr/bin/urlgrabber", line 124, in ? main() File "/usr/bin/urlgrabber", line 120, in main filename = urlgrab(url,filename=file,**kwargs) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 573, in urlgrab return default_grabber.urlgrab(url, filename, **kwargs) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 784, in urlgrab return self._retry(opts, retryfunc, url, filename) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 702, in _retry r = apply(func, (opts,) + args, {}) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 770, in retryfunc fo = URLGrabberFileObject(url, filename, opts) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 893, in __init__ self._do_open() File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 960, in _do_open fo, hdr = self._make_request(req, opener) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 1075, in _make_request raise URLGrabError(4, _('IOError: %s') % (e, )) urlgrabber.grabber.URLGrabError: [Errno 4] IOError: <urlopen error (2, 'No such file or directory')> Expected results: to properly get the file Additional info: i've tried FC4's python-urlgrabber rpm version python-urlgrabber-2.9.6-1 and get the same error, so I'm not sure where the problem lies. python-urlgrabber-2.9.6-1 worked fine on my computer when it was FC4 (I upgraded to FC yesterday). because of this problem, yum and pup do not work on my computer, and I need them to work for fedora updates.
I'm receiving this same problem as well. Here's what yum says: [root@Kremit yum]# yum update --disablerepo=livna Loading "installonlyn" plugin Setting up Update Process Setting up repositories core [1/7] Cannot find a valid baseurl for repo: core Error: Cannot find a valid baseurl for repo: core ...and with livna enabled: [root@Kremit yum]# yum update Loading "installonlyn" plugin Setting up Update Process Setting up repositories livna [1/8] http://rpm.livna.org/fedora/5/i386/repodata/repomd.xml: [Errno 4] IOError: <urlo pen error (2, 'No such file or directory')> Trying other mirror. http://livna.cat.pdx.edu/fedora/5/i386/repodata/repomd.xml: [Errno 4] IOError: < urlopen error (11, 'Resource temporarily unavailable')> Trying other mirror. http://wftp.tu-chemnitz.de/pub/linux/livna/fedora/5/i386/repodata/repomd.xml: [E rrno 4] IOError: <urlopen error (11, 'Resource temporarily unavailable')> Trying other mirror. http://ftp-stud.fht-esslingen.de/pub/Mirrors/rpm.livna.org/fedora/5/i386/repodat a/repomd.xml: [Errno 4] IOError: <urlopen error (11, 'Resource temporarily unava ilable')> Trying other mirror.

Error: failure: repodata/repomd.xml from livna: [Errno 256] No more mirrors to t ry. -------- I've removed yum and python-urlgrabber, then re-installed them, and the same error occurs. urlgrabber appears to be in its proper place: [root@Kremit yum]# ll /usr/lib/python2.4/site-packages/urlgrabber/ total 388 -rw-r--r-- 1 root root 16837 Oct 22 17:57 byterange.py -rw-r--r-- 1 root root 15122 Mar 14 15:58 byterange.pyc -rw-r--r-- 1 root root 14983 Mar 14 15:58 byterange.pyo -rw-r--r-- 1 root root 52875 Mar 14 15:58 grabber.py -rw-r--r-- 1 root root 47038 Mar 14 15:58 grabber.pyc -rw-r--r-- 1 root root 47038 Mar 14 15:58 grabber.pyo -rw-r--r-- 1 root root 2259 Feb 22 13:27 __init__.py -rw-r--r-- 1 root root 1706 Mar 14 15:58 __init__.pyc -rw-r--r-- 1 root root 1706 Mar 14 15:58 __init__.pyo -rw-r--r-- 1 root root 20230 Oct 22 17:57 keepalive.py -rw-r--r-- 1 root root 17814 Mar 14 15:58 keepalive.pyc -rw-r--r-- 1 root root 17814 Mar 14 15:58 keepalive.pyo -rw-r--r-- 1 root root 18069 Feb 22 13:26 mirror.py -rw-r--r-- 1 root root 16236 Mar 14 15:58 mirror.pyc -rw-r--r-- 1 root root 16236 Mar 14 15:58 mirror.pyo -rw-r--r-- 1 root root 18235 Aug 19 2005 progress.py -rw-r--r-- 1 root root 17015 Mar 14 15:58 progress.pyc -rw-r--r-- 1 root root 17015 Mar 14 15:58 progress.pyo My internet connection works fine, and the URLs that yum spits out work fine in a web browser.
Sorry for the extra e-mails, but I've found a solution to this problem and posted it here: http://fedoraforum.org/forum/showthread.php?p=478057#post478057 Please let me know if this fixes your issue. Basically, /etc/nsswitch.conf had an incorrect "hosts:" line, and copying over the default configuration (nsswitch.conf.rpmnew) took care of the problem. I believe that this was caused by a previous install of a package called mDNSresponder, required for the Gizmo Project (VoIP software). That install changed the hosts line to: hosts: files mdns nisplus dns Now for the speculation: After I upgraded to FC5, Avahi started conflicting with mDNSresponder (or mDNS just stopped working) and the "mdns" entry started causing all kinds of problems with yum, wget, etc. Oh well... I guess that's what I get for installing non-Fedora RPM packages, but it would have been nice to configure Avahi or otherwise have the installer check for something like this.
Wesley, copying /etc/nsswitch.conf.rpmnew over /etc/nsswitch.conf solved my problem. yum now works fine for me, thanks for the assistance.
