Some ppl are missing the point. Ignore any instructions that are telling you to repeat any upgrades - you clearly have a btrfs (filesystem) corruption that needs to be sorted out. I don’t use btrfs in a while but if you’re lucky then a ‘btrfs-check’ should be able to fix it. You need to boot from an install/live disk, and run the command on your disk, without installing, nor mounting the disk.










I was in a car with one of them there blu-ray players, and it turned out there was actually disc in, so we tried to use it. After 15 minutes of unskippable content, we finally got to the start of the film and wanted to select language/subtitles - and it wouldn’t let us. 20 mins wasted.
DVDs and BlueRay were crap, we just forgot.
