Description Florencio 2007-04-13 21:21:00 UTC
Description of problem:

"yum info updates" crashes on when there is an update for some packages,
like cups or selinux, when the summary have the symbol for "Registered 

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

How reproducible:

Steps to Reproduce:
1. yum info updates

Actual results:
UnicodeDecodeError: 'ascii' codec can't decode byte...

Additional info:

Changing line 73 in /usr/share/yum-cli/ as below solves the problem. 

print _("Description:\n%s") % pkg.description.encode("utf-8")

Comment 1 Jeremy Katz 2007-04-16 15:52:08 UTC
What locale are you running in?

Comment 2 Florencio 2007-04-16 16:47:09 UTC

Actually, it don't matter: after some tests, both UTF-8 and iso8859-1 really
works, not showing the error, but, "yum info cups | more", that was I always
doing, give the error. And, in this "more" case, the encode("UTF-8") thing
doesn't help...

Comment 3 G.Wolfe Woodbury 2007-04-18 13:06:41 UTC
This is the same bug that I have noticed with KYum, and there is a bz about this
pending that is being ignored.

Who's actually at fault?

Comment 4 Florencio 2007-04-19 22:44:51 UTC
The problem is:

get_file_encoding(sys.stdout) normally is "UTF-8", but when stdout is
redirected, we have "None".

/me forcing UTF-8 in

import sys
import codecs
sys.stdout = codecs.getwriter('utf-8')(sys.stdout)
sys.stdin = codecs.getwriter('utf-8')(sys.stdin)

Comment 5 Jeremy Katz 2007-04-25 16:58:02 UTC
Okay, I could reproduce this the other day and now I can't.

Summary: Common Unix Printing System

The Common UNIX Printing System provides a portable printing layer for
UNIX� operating systems. It has been developed by Easy Software Products
to promote a standard printing solution for all UNIX vendors and users.
CUPS provides the System V and Berkeley command-line interfaces.

Are you still able to reproduce it? 

Comment 6 Florencio 2007-04-25 23:08:16 UTC
Yes... and no:

# echo $LANG
# yum info cups | more
Loading "changelog" plugin
...some stuff omitted...
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 88: 
ordinal not in range(128)

# yum clean all
# yum info cups ==> OK
# yum clean all
# yum info cups | more  ==> surprise, it worked!

Yum downloading some (package info|metadata) with stdout redirected were
leading to error, but i can't reproduce it anymore...
I didn't see any change that could have fixed this, i'm confused...

Comment 7 Jeremy Katz 2007-04-26 18:26:40 UTC
New rhpl should be in tomorrow's rawhide that addresses some things like this. 
But I don't see how that would ever come into play with yum.

Can you give the full traceback?  I might be able to decipher then where we're
doing something wrong.  Or at least try

Comment 8 Florencio 2007-05-18 01:53:13 UTC
After some time without updates to those specific packages, today's
update choked up on policycoreutils. Full traceback:

Comment 9 Seth Vidal 2007-08-03 20:16:43 UTC
this is fixed up in yum 3.2.1 or 3.2.2 in fedora 7

please give them a try.
