Question Ubuntu update not showed in Plesk but showed when I login on SSH

[PeopleInside]

Server operating system version

Ubuntu 22.04.1 LTS

Plesk version and microupdate number

18.0.48

When I login by SSH to the server I see:

11 updates can be applied immediately.
To see these additional updates run: apt list --upgradable

When I login into Plesk UI there are no updates.
Are Plesk keep my server safe and need ignore what I see by SSH or I should install operative system update by myself?

If I go on system update and checking update I get:
The System Updates tool is already installing updates in automatic mode. Please try later.

This is an old error and issue on Plesk, never be able to resolve.


Thanks
