I just fixed another bug on my computer and now I don't know what's happening I can't log into my account the password Is correct and I changed it to be sure but when I try to log in a bunch of words pop up for a split second then disappear I haven't been able to read it all but it does say warning. Help me please! My computers bug was that I had stopped in the middle of an update and I would get a message saying that I had a file system error and a maintenance shell would be started so I fixed it by
mount -o remount,rw /
dpkg --configure -a
mount -o remount,ro /
sync
reboot
