Description of problem:

A python stack trace show when trying to execute 'dnf -y upgrade' as root.

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

- Fedora 22, fully up to date as of Sep 24th 2015.
- dnf-1.1.1-2.fc22.noarch

How reproducible:

Always




Steps to Reproduce:

On a system with a spanish locale, enter:


[root@bespin ~]# echo $LANG
es_ES.UTF-8
[root@bespin ~]# dnf -y upgrade

Actual results:

[root@bespin ~]# dnf -y upgrade
Traceback (most recent call last):
  File "/bin/dnf", line 36, in <module>
    main.user_main(sys.argv[1:], exit_code=True)
  File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 198, in user_main
    errcode = main(args)
  File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 84, in main
    return _main(base, args)
  File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 117, in _main
    cli.configure(map(ucd, args))
  File "/usr/lib/python2.7/site-packages/dnf/cli/cli.py", line 1007, in configure
    self.optparser.usage = self.optparser.get_usage()
  File "/usr/lib/python2.7/site-packages/dnf/cli/option_parser.py", line 273, in get_usage
    usage += "%-25s %s\n" % (name, summary)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 40: ordinal not in range(128)


Expected results:

Upgrade starts correctly.

Additional info:

When overriding the locale, it works as expected:

[root@bespin ~]# LANG=C dnf -y upgrade

[root@bespin ~]# 

It seems that there's some problem with an Unicode translated message for DNF, which is in the Spanish locale but not on the English one.
