Description Sylvia van Os 2018-05-20 22:41:34 UTC
Description of problem:
PackageKit fails to check for updates with the following error:

Fatal error: Error when getting information for file “/var/cache/PackageKit/28/metadata/taw-Riot/repodata/37cbbc0f7f939386c5c86248c02302b215339f73ba53af3bef1ef56e17bc644c-appstream.xml.gz”: No such file or directory

Noticeably, dnf works fine.

Version-Release number of selected component (if applicable):


How reproducible:
I'm not sure how it went wrong, but every update check simply fails with this error. Commands like "pkcon refresh force" and "pkcon update" fail in the exact same way.

Steps to Reproduce:
1. Run "pkcon update"

Actual results:
$ pkcon update
Getting updates               [=========================]         
Finished                      [                         ] (0%)  Command failed: Error when getting information for file “/var/cache/PackageKit/28/metadata/taw-Riot/repodata/37cbbc0f7f939386c5c86248c02302b215339f73ba53af3bef1ef56e17bc644c-appstream.xml.gz”: No such file or directory

Expected results:
PackageKit updates packages

Additional info:
This started happening after upgrading my Fedora 27 to 28. The update otherwise went flawlessly for as far as I can tell. I've already tried "sudo dnf clean all" as well, with no success. I was told on IRC to report this on the bugtracker.

Comment 1 Rex Dieter 2018-05-21 01:22:02 UTC
It appears you're using a repo that claims to support appdata but doesn't actually provide it.

Comment 2 Sylvia van Os 2018-05-21 13:47:52 UTC
Made an upstream report to https://github.com/taw00/riot-rpm/issues/14, which is the upstream behind https://copr.fedorainfracloud.org/coprs/taw/Riot/. Still odd to me that PackageKit has issues with it that completely break PackageKit (cannot update anything else through it anymore either), but dnf will update from this repo just fine.

Comment 3 Rex Dieter 2018-05-21 19:13:02 UTC
dnf doesn't use appdata, if the repo does not include appdata, it should not include:
enabled_metadata=1

Comment 4 Rex Dieter 2018-05-21 19:14:00 UTC
Possible it's a copr bug, I've seen several cases are appdata doesn't get generated properly.

Comment 5 Todd Warner 2018-05-27 05:09:31 UTC
riot provides appdata as is required for desktop applications...
```
[todd@localhost ~]$ rpm -ql riot |grep appdata
/usr/share/metainfo/riot.appdata.xml
```

I'm not sure I understand the issue.
Note: I am the maintainer of this RPM. If I am doing something incorrectly, I would love to know. Thanks!

Comment 6 piglist 2018-08-23 10:05:45 UTC
This is an issue with tons of COPR and third-party repositories. And for some reason the entire repo refresh operation will fail just because you have one repo without valid appdata.

Something really has to be done about this as soon as possible if the GUI updater is to remain reliable.

Comment 7 Matthias Runge 2018-09-21 06:22:46 UTC
I see this issue for disabled repos.

Fatal error: Error when getting information for file “/var/cache/PackageKit/28/metadata/rpmfusion-nonfree-nvidia-driver/repodata/appstream.xml.gz”: No such file or directory

There seems to be something fishy with this.

However, I can confirm, making sure
https://bugzilla.redhat.com/show_bug.cgi?id=1580162#c3
this works around the issue.

Comment 8 Mikel Pérez 2018-10-28 23:49:19 UTC
it also breaks package install suggestion on the console when it cannot find a program in the PATH

Comment 9 Gergely Gombos 2018-11-07 20:48:37 UTC
Getting the same issue on F29, breaking GNOME Software updates.
$ sudo pkcon refresh force -c -1
