Can't upgrade to Plesk 8.2

[JulianHH]

Hi there!

I just wanted to upgrade to Plesk 8.2 (I have 8.0), but the update fails. I get the mail with the following attachment (excerpt):

Install package psa-autoinstaller-3.2.0-build32070705.20.x86_64
rpmdb: PANIC: Invalid argument
rpmdb: PANIC: fatal region error detected; run recovery

error: error(-30978) getting "psa-autoinstaller" records from Name index
rpmdb: PANIC: fatal region error detected; run recovery

and so on, and so on..

this also happens, when I try to upgrade to 8.1..

Is there anyone who may help me?
Thanks in advance!

kind regards,
Julian
