I get an error message that a required upgrade file is missing. I ran in terminal a ubunut-bug entry as requested.

[Bill Young]

Description: Ubuntu 22.04.4 LTS
Release: 22.04

~$ apt-cache policy pkgname
N: Unable to locate package pkgname

I get the what seems to be a permanent message: "Software catalog is being downloaded"

Seems to me that something has gone wrong as Ubuntu tried to automatically upgrade my computer.

I will reboot to see if things improve.
