Prehistory what caused it.
It was Linux 5.15.53-1-pve #1 SMP PVE 5.15.53-1 (Fri, 26 Aug 2022 16:53:52 +0200)
decided to upgrade, performed apt update and upgrade, then forgot to restart the server and performed apt autoremove, and at the time this command was executed, the server was overloaded, after which the PBS became unavailable, when you try to upgrade, errors fall
root@Host022:~# apt update && apt install pve-kernel-5.15

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
pve-kernel-5.15 : Depends: pve-firmware but it is not going to be installed
Depends: pve-kernel-5.15.108-1-pve but it is not going to be installed
util-linux-locales : Depends: util-linux (>= 2.36.1) but 2.33.1-0.1 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
