Question osdetect failed: Error: Cannot determine version scanning ""

[cool_sh]

Server operating system version

CentOS 7

Plesk version and microupdate number

18.0.65 #2

Hi all,

which files or database tables does plesk use to determine th ecurrent OS ?

I have the problem that i can not install updates or plugins due to the named error:
Fehler: osdetect failed: Error: Cannot determine version scanning ""

But: the "standard" files exist and show correct information:
- cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)

- uname -r
3.10.0-1160.119.1.el7.x86_64

And inside Plesk I see the correct version on different sides like the page after login or in server information:
Version: Plesk Obsidian v18.0.65_build1800241122.08 os_CentOS 7
Betriebssystem: CentOS Linux 7.9.2009 (Core)

Hello!

osdetect tries to check following files /etc/debian_version, /etc/CloudLinux-release, /etc/vzlinux-release, /etc/almalinux-release, /etc/rocky-release. If one of these files exists and has empty first line, osdetect can fail with such error. Could you please check your server?
