Plesk 8.0 to 8.1 upgrade problem

[SzymonK]

Hi,

I've tried to upgrade Plesk from 8.0 to 8.1, and there is error:

Install package psa-qmail-1.03-fc4.build81061129.22.i586
Checking for the system groups and users necessary for Qmail...
Checking for the group 'qmail'...

ERROR: It seems there is a group with GID=2520
in this system, but Plesk needs the same GID
for its operation.
Unfortunately, this situation has not yet been
resolved.
Please, visit http://www.swsoft.com/support for assistance.

Exiting...
