Mint 22.1 still runs Kernel 6.8 whoch means you’ll be hitting the terminal to either upgrade to mainline kernel
The last two major updates of Mint were done through some GUI. There were a few warnings (about a few extra apps I had installed) but everything was done through that app and went smoothly. Edit: and so quickly (yeah, I'm looking at you, macOS)
or add extra repositories
I don't think I use extra repositories but I did add two PPAs and did it through the GUI 'Software Sources' that comes with Mint. I just checked, it also offers the option to add 'Additional repositories', if that means 'extra'?
I'm not much of a gamer (I play chess, though), I only wanted to say I needed no 'fix' nor terminal in order to get my Mint to update to its latest versions ;)
