Error: Failed to configure the up2date utility. Command python exit with non-zero status (1).

If you are receiving this error within the Plesk updater when you try to upgrade plesk 8.2 to 8.2.1 you will need to take a look at the file

==
/etc/sysconfig/rhn/up2date
==

and make sure that the line with

==
pkgSkipList
==

has a semicolon in the end.

Here is a sample and the link which had this info.

BEFORE
==
pkgSkipList[comment]=A list of package names, optionally including wildcards, to skip
pkgSkipList=
==

AFTER
==
pkgSkipList[comment]=A list of package names, optionally including wildcards, to skip
pkgSkipList=;
