I am trying to upgrade my Plesk Panel 11.0.9 to 11.5.30 on my Ubuntu 12.04 but facing the following error
unable to start piped log program '/opt/psa/admin/sbin/pipelog 7081': No such file or directory Unable to open logs
There is no pipelog file in the filesystem.
Create the pipelog file with the following command
Grant the following permissions to the created file:
chmod 750 /opt/psa/admin/sbin/pipelog
Restart the upgrade process with the autoinstaller.
