Resolved Install Plesk 18.0.42 on Debian 11

[HoracioS]

Hello,

I'm trying to install Plesk on Debian 11 and got this message regarding bullseye-backports installed by default in Ubuntu 11:

Reading package lists...
Retrieving information about the installed license key...
Launching component and product checkers...
Downloading file pool/PSA_18.0.42_8382/examiners/repository_check.sh: 100% was finished.

Downloading file pool/PSA_18.0.42_8382/examiners/sh_cmd.sh: 100% was finished.

Components and product validation detected at least one important issue:
Enabled repositories check
Plesk installation doesn't support 'Debian Backports/bullseye-backports/non-free' OS repository.
Make sure it is disabled, then try again.
Plesk installation doesn't support 'Debian Backports/bullseye-backports/contrib' OS repository.
Make sure it is disabled, then try again.
Plesk installation doesn't support 'Debian Backports/bullseye-backports/main' OS repository.
Make sure it is disabled, then try again.

Proceeding with installation or upgrade without resolving the issues
that were found can corrupt your data.

Do you want to continue? [y/n]:

My question is I really need to disable them.

Best regards,
Horacio

I would advise doing what is suggested to avoid later problems and questions about package conflicts, inconsistencies and so on.
