gitlab init: postgres unused client(s) uninstall fails

[xaviersand]

Hi,

i could successfully run a gitlab selfhosted on my local computer.
when i try to run the docker-compose.yml on my proxmox 8.1 hypervisor. (i have a LXC contain running other docker containers)
I encounter this error in the gitlab container.

gitlab-1         | E: Sub-process /usr/bin/dpkg returned an error code (1)

I started the gitlab container with a bash console and tried to delete these to have a better error message:

(Reading database ... 22245 files and directories currently installed.)
Removing postgresql-contrib (17+267.pgdg22.04+1) ...
dpkg: error processing package postgresql-contrib (--remove):
 cannot remove '/usr/share/doc/postgresql-contrib': Invalid argument
dpkg: too many errors, stopping
Errors were encountered while processing:
 postgresql-contrib
Processing was halted because there were too many errors.

it looks like it's trying to delete '/usr/share/doc/postgresql-contrib' , i don't know if it should or not (i'm not a postgres expert), but i can't.
