  • Plesk 11.5 for Linux


I'm trying to upgrade Parallels Plesk Panel using the GUI to version 11.5.30 however whenever I try it comes back with the following information in the log:

Trying to add group 'psacln'... groupadd: group 'psacln' already exists

ERROR while trying to add group 'psacln'
Check the error reason(see log file: /tmp/plesk_11.5.30_installation.log), fix and try again


Group "psacln" is duplicated on the server:

~# cat /etc/group | grep psacln


Remove the second user and restart Plesk upgrade. For removing the group:

  1. Backup file /etc/group:

    ~# cp /etc/group /etc/group.bak
  2. Open the file in file editor with the "vigr" command:

    ~# vigr
  3. Find the second records for group psacln and remove it:

  4. Save the file.
