Question blocked at Plesk Obsidian 18.0.40 (dec 2021) !

[silvioDacey]

Server operating system version

Debian 9.13

Plesk version and microupdate number

18.0.40

As the title says, I am blocked on Plesk Obsidian 18.0.40, dated dec 2021 !
The only upgrade Plesk proposes is to 18.0.44, which fails : "There is no product aailable for your OS 'Debian' 'Linux' '9.13' 'x86_64' .
I am stuck here, with old versions of php and MariaDB. Why ?
How can I move forward ?
Thank you.

I am stuck here, with old versions of php and MariaDB. Why ?

Because you're running an outdated OS, which has been EOL for a number of years now and hence is no longer supported by Plesk.

How can I move forward ?

Upgrade your server to a new Debian release. Debian 10 is the lowest supported version by Plesk when if your license includes Extended Lifecycle Support (ELS). Otherwise Debian 11 is currently is oldest supported Debian releases without ELS. Information on how to upgrade your Debian release can be found here.

Alternatively you could migrate to another server running a supported OS (like for example Debian 13 or Ubuntu 24.04).

Also see Plesk Lifecycle Policy.

Thank you for your answer. I did'nt realize that I was running on such an old OS version.
I am going to migrate to Debian 13.

Be wary with Debian 13, as I had issues restoring a full server backup (taken on Debian 12).

Issues were mainly to do with any Apache sites not working at all, and this was on a fresh Debian 13 install NOT an in-place/dist-upgrade from Debian 12 to 13.

I had to reinstall the server back to Debian 12 then restore the backup which worked fine afterwards.

See here for the Apache issue I had.

You should always do a migration using the migration wizard if all possible. Restoring from backup should be the last option as restoring from backup is usually meant when the server has issues and need to spin up a new one thus not being able to do the migration. This way you can keep the old one active while getting the new one ready while syncing the changes from old to the new.

I am on OVH. They don't propose Debian 13 but only Debian 12 at this time. So I am going to migrate to Debian 12.
Thank you for your warning.
