My home desktop computer runs Ubuntu 20.04 LTS with German as the interface language. This morning, for maybe the first time, I've seen an unidentified modal window three times that demands a password. Because it's modal, I have not been able to take a screenshot with Ubuntu's screenshot app.
Roughly translated from memory, the message says something like, "Verification required. Your digital keyring was not automatically unlocked. Please enter the password."
Because the window does not say "Ubuntu" or any application name, I don't know who's asking or what password it's asking for. I can hit cancel and keep working, but the window keeps coming back.
Does this ring any bells with you? Any ideas what this window might be?
