Issue Plesk Installer doesn't work anymore

[SirSeba]

Server operating system version

Ubuntu16.04

Plesk version and microupdate number

18.0.34.2

Hello everyone,

the plesk installer stopped working for some reasons.
I cant install/update components from plesk installer either from the CLI or from Plesk Panel.
When I try to run the command "plesk installer update" , I get the error "No products installed yet. First you have to use the command "install", in order to install products".
Plesk -v output is:

Product version: Plesk Obsidian 18.0.34.2
OS version: Ubuntu 16.04 x86_64
Build date: 2021/03/25 10:00
Revision: e5a6bfface98f8934d483a7a2fcdcc53195bda68

I know that Ubuntu 16.04 is End of Life, I will upgrade it to a higher version but I am still figuring it how ..

Operating system is out of support and I am afraid the quite old Plesk version is, too. Plesk does not work on products that are end of life. I suggest migrating to a new server with a current operating system. That can either be done using Plesk Migrator or by a restore of a full backup.

Thanks for the reply @Peter Debik.
Migrating to another server would be hard as this is a hosted dedicated server and I would need to purchase a new one in order to migrate it to.
Do you recommend to create a full backup, reinstall the server on the new version and then restore the Plesk Configuration/Files from the backup?
Or do you think that with the dist-upgrade I could upgrade the server without damaging it?

You can perform a dist-upgrade with this instruction, but read the article AND the comments from other users before you even start.
And as always, create a backup of your current server:

I would advise starting with a new server and migrating the accounts. You can apply for a Plesk migration license:
