It just randomly started. My computer will still search for updates but it won't install them. I have 35 updates that need installing, and if I were to shut down my computer, it would say: "installing 22 of 35 updates" Then it'd shutdown without finishing the updates. It would do the same if I were to start it up, but afterwards it's say: "Failed to install updates. Reverting changes." Then it'd restart.
I have no idea what is going on, but if somebody could help me out, I would really appreciate .
