Please be patient and guide me step by step i am a linux noob.
This error occurs when booting. Either that or my crypt' password page shows up and i can't put in the pw. However i can start ubuntu's recovery mode. When i tell him to repair packages he does so and asks me for the crypt pw on command line - then somewhere he has the errno -32 again but "tries after 8 seconds" and is running fine. Then i can start ubuntu normal from the recovery mode page. I also tried telling him to update grub, which doesn't affect anything.
