Description Mads Kiilerich 2009-09-28 13:31:02 UTC
Description of problem:

Trying a yum upgrade from F11 to rawhide I got:

/usr/lib/python2.6/site-packages/yum/packages.py:413: UnicodeWarning: Unicode unequal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
  if reqn != n:

It is caused by 
reqn=u'ttfonts-ja'
n='font(\xe3\x81\x95\xe3\x81\x96\xe3\x81\xaa\xe3\x81\xbf\xe3\x82\xb4\xe3\x82\xb7\xe3\x83\x83\xe3\x82\xaf)'


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

yum-3.2.24-2.fc11.noarch

does this happen every time and if you run:

yum clean all

does it go away?

Comment 2 Mads Kiilerich 2009-10-13 11:40:40 UTC
I see it every time on this machine (which won't be upgraded before the totem-upgrade has been solved ;-)). Cleaning makes no difference.

[root@localhost ~]# rm -rf /var/cache/yum/*
[root@localhost ~]# yum --enablerepo=rawhide upgrade

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
[root@localhost ~]# rpm -q yum rpm-libs
yum-3.2.24-2.fc11.noarch
rpm-libs-4.7.1-3.fc11.i586


Some thoughts:

Obviously there is disagreement about whether unicode or utf-8 strings should be used. Which of them are wrong?

Could it be related to
[root@localhost ~]# repoquery $(rpm -q --provides sazanami-mincho-fonts|grep -v =)

yum.Errors.RepoError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings.

"yum install 'font(さざなみゴシック)'" should work, right?

Comment 3 Mads Kiilerich 2010-01-13 22:58:40 UTC
The system was upgraded to F12 by bruteforcing package problems, so it is no longer a urgent problem for me, and I'm not sure I can reproduce it.
