Authentication Problem, Software Boutique and Synaptic

Hi. Since I already copied/pasted commands from the Internet to my machine, which you said is a path to disaster, I was wondering what you would suggest I do? Should I try to get a clean copy of Jammy to USB, then wipe the installation and restore from a backup of the home directory?

Hi again!

I think applying instructions from the Internet without understanding may harm your system.

Why do you want to reinstall? It looks like you have resolved your initial issues in this thread.

Jammy is version 22.04 with 3 years of support. This support period will end soon. A newer LTS version is Noble (24.04).

Hi @ironfoot Even on this site I need to exercise caution? The only thing that doesn't work, and I really, really wish it would is Cairo Dock-- there are so many different UI's I could make if it would. I also wish the Advanced Menu (mate menu) would work--I edited the applications.list to get the order appear as I want--I click it and nothing drops down. I don't have notifications from meteo-qt weather, but this is okay; I still see the temperature in the panel. I have Ubuntu Pro, so I don't want to mess with an upgraded system that doesn't run some program I use, be it some Steam game or some Wine or Dosbox game, so I am thinking of not upgrading until 2032--cool? I had the Ubuntu Precise, then upgraded and lost use of Celestia-- had lots of stuff installed, too.

It's a friendly and helpful community, but it's an open public forum. Take everything strangers (like me) write on the Internet with a grain of salt.

I see you still have different specific questions about different software. To discuss these issues, it is better to open separate new topics (or raise existing ones). This topic is about authentication problems and is marked as resolved.

As an experiment or proof of work -- maybe. You'll have a severely outdated system by then. I believe the majority of users are upgrading their systems, and they are the ones generating the major part of the feedback and collective knowledge. And you will be able to get very limited community support with your unique setup after a few years.

Ok-- thanks for the info; guess I'll upgrade. It's free, after all-- Windows 10 would be another issue.
