Resolved Unable to update Debian, Obsidian

[TinaBura]

Server operating system version

Debian

Plesk version and microupdate number

18.0.44

Hi,

I am unable to update Plesk on my server anymore. It shows:
OS: Debian 9.13
Product: Plesk Obsidian 18.0.44 Update #3

If I go to Tools & Settings and click on Plesk Update, the link for "Install or Update Product" is inactive (grayed out).
If I go to Tools and Settings I see the Error: The System Updates tool is already installing updates in automatic mode. Please try later.

I have paid Plesk support, but I cannot create a ticket as I am more than 2 versions behind the latest update

Please help. Where should I start now?

Thanks!

Thats because Debian 9 has reached it's End-Of-Life status and is no longer supported by Plesk. As you've already discovered.

If you're up to it, you can upgrade you server to Debian 10 and then to Debian 11. Which is explained in detail here: https://support.plesk.com/hc/en-us/...upgrade-procedure-on-Linux-server-with-Plesk-

Hi, thank you!

I have tried to follow the guide, but after I execute 'apt-get update && apt-get upgrade' (step 7) I see this error:

Unable to get packages list: 2023-01-02 16:47:59 INFO: pum is called with arguments: ['--list', '--repo-info', '--json'] 2023-01-02 16:48:00 ERROR: E:The repository 'https://dlm.mariadb.com/repo/maxscale/latest/apt stretch Release' does no longer have a Release file. 2023-01-02 16:48:00 ERROR: Exited with returncode 1.

My MariaDB Version is 10.2 if it matters.

Yeah, MariaDB 10.2 also reached end-of-life. Try to upgrade to newer MariaDB version first. For example 10.6. Steps explained here: https://support.plesk.com/hc/en-us/articles/213403429

Beware that for MariaDB 10.6 does not bind to both ::1 and 127.0.0.1, like it does on older versions. So after the MariaDB you'll probably have to perfrom some extra steps: explained here.

Thank you a lot! It's a bit chaotic now. I have managed to get this:
OS: Debian 10.13
Product: Plesk Obsidian 18.0.49 Update #1

The server and Plesk run both. All projects (PHP+MariaDB) are running.

But MariaDB is still 10.2.

I still see the Error: The System Updates tool is already installing updates in automatic mode. Please try later. under Tools and Settings -> System Updates
And my Plesk shows now additional message: Upgrade failed. To remove this notice, remove the file /var/lock/parallels-panel-upgrade-failure.flag from the server. Repair the failed upgrade or installation.

I will try with support tickets from here, as I have obviously the latest Plesk version now.

Your help was very appreciated! Thank you!

Follow-up: All my errors have been resolved by support. There were issues with Plesk Update Manager because the underlying Linux operating system was unable to perform package installations or updates. The Plesk upgrade installation has been successfully repaired.
