- Plesk for Linux
Plesk 12.5 is loading forever after dist-upgrade from Debian 7 to Debian 9:
# plesk version
Product version: 12.5.30 Update #70
Update date: 2017/09/27 16:57
Build date: 2016/06/08 10:00
OS version: Debian 9.4
The following confirms that OS was upgraded recently in
CONFIG_TEXT: Start-Date: 2018-03-24 20:06:18
Commandline: apt-get dist-upgrade
Running Plesk installer from CLI results in only 1 point available for installation without marking Plesk as already installed:
# plesk installer
1. [ ] Plesk
Unable to retrieve the password for Plesk GUI, the command is running endlessly:
# plesk bin admin --show-password
Such a dist-upgrade is not supported: Plesk 12.5 does not support Debian 9.
The following operating systems are supported by Plesk 12.5:
Debian 7 (32-bit and 64-bit)
Debian 8 (32-bit and 64-bit)
Ubuntu 12.04 (32-bit and 64-bit)
Ubuntu 14.04 (32-bit and 64-bit)
CentOS 5.x (32-bit and 64-bit)
CentOS 6.x (32-bit and 64-bit)
CentOS 7 (64-bit)
Red Hat Enterprise Linux 5.x (32-bit and 64-bit)
Red Hat Enterprise Linux 6.x (32-bit and 64-bit)
Red Hat Enterprise Linux 7 (64-bit)
CloudLinux 5.x (32-bit and 64-bit)
CloudLinux 6.x (32-bit and 64-bit)
CloudLinux 7.x (64-bit)
The following may be done to restore the server:
- Restore the server to a pre-upgrade state from a server backup or snapshot so that Plesk and server OS are reverted to a correctly configured state.
- Restore a backup made on a pre-upgraded server on a new server that satisfies Plesk 12.5 system requirements.
- Migrate to another server that satisfies Plesk 12.5 system requirements.
The correct way to perform a dist-upgrade on a Debian 7 server with Plesk 12.5 is upgrading server OS to a supported version: Debian 8. Do not upgrade server OS to Debian 9 with Plesk 12.5!
