@Ladyslayer0160 sorry to bring this up. I just got the same problem. I can't use the keyboard or joystick up and down after update. but works fine in terminal. Have you resolve this issure yet? Thanks!
@rbaker yes I read that mate, good advice but the (RetroPi) SD Card is totally unreadable in any OS I put it in 3 different SD card readers the pc does the 'dur doop' noise to signal new hardware detected but nothing, the best I had was 'removable disk' in Windows Explorer show up and I tried to format only to be told 'F is unreadable' I tried ChkDsk in DOS similar outcome ... All a bit brutal mate, time the SD card met the bin, but I would hope to not have to throw away the Pi too
It is never planned that stuff you have set-up breaks, but I can't guarantee it hence backing up first. Sometimes certain packages are reworked in a way that isn't very backward compatible, but backup - try and update and then post if you need help ?
