Autoinstaller fails to detect MU10 when group "qmail" is missing

[Monty]

Hi

I noticed that our Plesk 9.5.4 installations (CentOS 5.7 x86_64) failed to detect the latest microupdate (MU10). On the GUI no components updates were displayed.

I ran autoinstaller manually:

# /usr/local/psa/admin/bin/autoinstaller --check-updates

Group named 'qmail' is not exists on this system.

(We are using postfix and not qmail).

After doing groupadd qmail the updater worked fine again and MU10 was installed.

Just wanted to let you know in case anyone of you runs into the same problem.
