Failed to contact accountsservice

Hello

I’m new in linux univers and built a server on Ubuntu 20.04 desktop.

I recently install cockpit and saw that there is an error. I googled the error message without finding any solution.

The error is linked to gdm3 which is Gnome 3.

On cokcpit, I have the following message

Failed to contact accountsservice: Erreur lors de l’appel de StartServiceByName pour org.freedesktop.Accounts : Refusing activation, D-Bus is shutting down

I checked the status of gdm3.service and there is the following error (In orange on my computer and strong below)

thierry@Server-TH:~$ systemctl status gdm3.service

it seems there is a problem with gkr-pam: no password is available for user

Did someone already have this issue?

Thanks in advance
