Description Berend De Schouwer 2013-05-14 09:41:46 UTC
Description of problem:

Software update fails with:

Error Type: <type 'exceptions.UnicodeDecodeError'>
Error Value: 'ascii' codec can't decode byte 0xc2 in position 49: ordinal not in range(128)
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 3590, in <module>
    main()
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 3587, in main
    backend.dispatcher(sys.argv[1:])
  File : /usr/lib/python2.7/site-packages/packagekit/backend.py, line 722, in dispatcher
    self.dispatch_command(args[0], args[1:])

    print("details\t$s\t$s\t$s\t$s\t$s\t$ld" $ (package_id, package_license, _to_utf8(group), _to_utf8(desc), url, bytes), file=sys.stdout)



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

gnome-packagekit-3.8.1-1.fc19.x86_64


How reproducible:

It depends on software updates available.  Not all updates trigger the problem.  I've had it in the past with different characters, eg.
Error Value: 'ascii' codec can't decode byte 0xe2 in position 111: ordinal not in range(128)


Steps to Reproduce:
1. Run software update (or gpk-update-viewer)
2. processes for a little bit
3. Error appears

  
Actual results:

Error appears


Expected results:

No error.


Additional info:

In this particular case I was able to trap the "bad" line (unicoded, unfortunately):

possible fix

possible fix.  Just wrap more parameters in _to_utf8()

Comment 3 Berend De Schouwer 2013-05-14 10:18:13 UTC
I can't see an actual reason for unicode in http://www.selinuxproject.org/, policycoreutils;2.1.14-40.fc19;x86_64 or GPLv2.  There are in description, but that was already _to_utf8()

Character 49 matches 'M-BM-' in 'LinuxM-BM-', which is (r)egistered, and matches 0xc2, but that's in description.  And description was already _to_utf8()

I'd have to guess a Python 2.7 auto up/down cast between str() and unicode() types bug.

Comment 4 Richard Hughes 2013-12-11 09:09:53 UTC
I've fixed a load of these kind of problems in f20, can you try there please?

Comment 5 Berend De Schouwer 2013-12-11 09:23:25 UTC
I am running F20 beta now.

F20 seems to have had no updates (all mirrors are empty) for at least a week, so I'll test after F20 final comes out.

Comment 6 Rex Dieter 2013-12-11 12:42:02 UTC
The f20-not-working-for-a-week thing is likely that you got a bad yum update,
https://admin.fedoraproject.org/updates/FEDORA-2013-22706/yum-3.4.3-119.fc20

the fix is here:
https://admin.fedoraproject.org/updates/FEDORA-2013-22841/yum-3.4.3-120.fc20

Comment 7 Berend De Schouwer 2013-12-11 12:53:47 UTC
Still on yum-3.4.3-111.fc19.noarch

Following:
https://mirrors.fedoraproject.org/metalink?repo=updates-released-f$releasever&arch=$basearch

gives me a very limited mirror list (3 sites), and those are basically empty (< 1 kB) hash-filelist/other/primary.gz/bz2.

(never before noticed the mirror list is only 3 sites -- "ZA" and "NA" locations -- I'll have to play with my location settings.)

Comment 8 Berend De Schouwer 2013-12-11 13:00:11 UTC
'kay, different location does have updates (not as many as expected)

Comment 9 Berend De Schouwer 2013-12-11 13:49:10 UTC
First run of gpk-update-viewer went fine.

Comment 10 Berend De Schouwer 2013-12-11 13:55:52 UTC
Downgraded policycoreutils, and used gpk-update-viewer to update it.  Updated fine with unicode in package description.

Comment 11 Fedora End Of Life 2015-01-09 22:07:01 UTC
This message is a notice that Fedora 19 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 19. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 19 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 12 Fedora End Of Life 2015-02-18 13:53:46 UTC
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
