I was updating my Ubuntu LTS and we had a power outage. Now, when I try to "sign in", I get a "failed to start session" message in bold red under my main and guest accounts. I'm not sure how to fix this.
I'm also unable to connect to the Internet. I have tried (Ethernet, WiFi, and Hotspot)
When I try signing in with the wrong password on the main log-in screen, it says "invalid password", but when I use the correct password it says failed to start the session when I try to sign in using Ctrl+Alt+F2 it says login incorrect.
