Description Michal Domonkos 2019-08-22 15:34:10 UTC

This bug was initially created as a copy of Bug #1425776

I am copying this bug because: 



I receive error message from yum-cron (daily, yum-cron is set to emit message by email) because of encoding error:

yum-cron:230:sendMessages:UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 76: ordinal not in range(128)

This line 230 contains:

output = ''.join(self.output)

The output is in UTF-8 (and not in ASCII) probably because I'm using cs_CZ.UTF-8 locale. Similar bug has been fixed in the past, see bug #1202680

Traceback is attached.

*** HOW TO TEST ***

To test this, you'll need to trigger yum's import mechanism for GPG keys when installing the downloaded updates.  The reason is that, in case of a missing key, the Czech translations of the error message contains the word "klíč" which would previously trigger the traceback.  With the patch, the error message is decoded into a proper unicode object.

Setup:
# yum install -y glibc-common  # for localization support
# rpm -qa ^gpg-pubkey | xargs rpm -e  # remove all RPM public keys
# cat /path/to/yum-cron.conf
[...]
update_messages = yes
download_updates = yes
apply_updates = yes
[...]

Test:
# LANG=cs_CZ.utf8 yum-cron /path/to/yum-cron.conf

Result (before):
[...]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 76: ordinal not in range(128)

Result (after):
No crash, just the regular output.
