Issue Plesk not installed, no system packages

[RJ45]

Server operating system version

CentOS 7.9

Plesk version and microupdate number

Plesk Obsidian 18.0.65 Update #2

I am using CentOS 7.9 and am experiencing problems when updating.

When checking for updates, it says that Plesk isn't installed. Then, when I attempt to run an update, I get the following error:

Enabled repositories check
http://vault.centos.org/centos/$releasever/os/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
Trying other mirror.
To address this issue please refer to the below wiki article

Additionally, some packages within Plesk are not working correctly. I can no longer change PHP versions, and Postfix appears to not be installed, despite it actually being installed.

Hello, @RJ45 . I attempted to reproduce the issue on a CentOS 7.9 server by updating from Plesk 18.0.65 to .69 and everything went as expected. Could you please confirm if you have ELS currently active for the server in question, please?

Hello @Sebahat.hadzhi

ELS it not activated. Iam running a Digital Ocean droplet.

Thank you for the confirmation. It seems like the file in question is present under:

• https://vault.centos.org/centos/7/os/x86_64/repodata/repomd.xml
• https://vault.centos.org/centos/7.9.2009/os/x86_64/repodata/repomd.xml

So, my guess is that something is going wrong with the interpretation of the $releasever. What I can suggest is to try editing the baseurl values and replace $releasever with 7 in /etc/yum.repos.d/CentOS-Base.repo at your own risk. Please do make sure to create a snapshot, or at least a copy of the file before you proceed.
