[10:11] <arraybolt3> xu-irc58w: For in the event you look at the logs, Ubuntu 19.10 is out of support and has been for a few years now. The easiest and best way to fix this problem is to download the latest Xubuntu 22.04.1 ISO from the official website, back up your data, and install Xubuntu from scratch.
