[CentOS] Can't update

Hi,

I can't do update:

yum update Traceback (most recent call last): File "/usr/bin/yum", line 29, in <module> yummain.user_main(sys.argv[1:], exit_code=True) File "/usr/share/yum-cli/yummain.py", line 298, in user_main errcode = main(args) File "/usr/share/yum-cli/yummain.py", line 110, in main base = cli.YumBaseCli() File "/usr/share/yum-cli/cli.py", line 72, in __init__ output.YumOutput.__init__(self) File "/usr/share/yum-cli/output.py", line 307, in __init__ self.reported_error_msgs = dict((k, False) for (k, v) in ERRORS_TO_KBASE_ARTICLES.iteritems()) NameError: global name 'ERRORS_TO_KBASE_ARTICLES' is not defined

Any suggestion ?

Thank's​
