I cant upgrade proxmox

[major caveira]

I am trying to upgrade the proxmox, but I am getting the error mesage:

Starting system upgrade: apt-get dist-upgrade
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

But everytime that I run the command 'dpkg --configure -a' the computer simple restart without warning or error. Now I am stuck without the upgrade possibility.

Any ideas, please?

Proxmox version 9.1.2
