I've tested this now, it seems to work fine.
I'm asking here as there doesn't appear to be a thread for Linux.
I'm a mod from the Classic Gaming Discord and we have loads of MiSTer users on there, I've just seen the new update with the warning and I want to try and get ahead of the game with this. For people who update without also updating Linux, is there a known fix for people who've done that?
I know the updater script has been updated now top take this into account but I know people are going to get it wrong and probably come running to us for advice so I'd quite like to get ahead of this.
