Like a few others, I seem to be experiencing difficulty with the 3.5.5 update. I’ve tried several times and several different ways, but the update just won’t take, throws an error when I try applying it.
Thankfully, it hasn’t broken broken anything as far as I can tell. However, whenever I reboot, it tries booting into the broken update and gives me the GNU GRUB menu that throws an error whenever you try to do anything. That’s relatively easy to get past, I just hold the (…) when attempting a reboot, and it gives me the functional OS partition (“Previous A”) again. That being said, every time I reboot now, it still gives the busted GNU GRUB menu. I’m glad my Deck isn’t broken and no data is lost, but I’d really like to not have to do this every time I reboot. Is there a way to clear the “Current B” partition without screwing anything up?
When booted into your working partition, go to desktop mode and run the following command in konsole. It will set the currently booted partition as default instead of your broken one.
