Try uninstalling Steam (or keeping track of which one was already installed), and trying one of these methods. It was over a year ago I last did this, so I don’t 100% remember which version I ended up using but believe it was the Flatpak version that worked best.
For graphics drivers updating, MintOS has a GUI interface for managing drivers which is actually pretty nice. Try searching for Driver Manager in your system utilities. Other than that, you can manually download official AMD drivers from them directly here. I’d recommend looking into that process for Linux a little more before going that route, as there are a few CLI commands you’ll have to use.
As for updating anything, yes it will mostly be done the same way you installed in the first place if you used the CLI. Try the following:
sudo apt-get update
sudo apt-get upgrade
Maybe that works for internal and business communications, but if it is communication externally with clients there are a lot of people that just don’t answer their phone. Sometimes it is important stuff, and sometimes there are followup questions.
“XYZ is no longer available. Would you like ABC instead?
How many of ABC would you like?”
