This happened after a kernel update. Whenever I try to boot, my computer says "Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1) Welcome to emergency mode!..." followed by abunch of things I can do. It spits the same error out if I ctrl-d to boot into default mode, and the fstab file matches the drive UUIDs perfectly. But I think I found the culprit. When I run blkid, it takes a while, and then spits out "blk_update_request: I/O error, dev fd0, sector 0" followed by the drives' data. What is happening, why, and how do I fix it?
I tried the possible duplicate question, but it is a slightly different error and the solution doesn't work.
