I have Ubuntu 18.04 with unity desktop installed. It was working fine. Once I tried to Force Shutdown(Holding power button). After that It did not login. After entering password It shows a black screen and comes back to login screen. It's the same described in Ubuntu gets stuck in a login loop but none of these solutions work for me. After logging in to shell whenever I enter a command it shows something like this
command mv is located in /usr/bin mv cannot be loaded because /usr/bin has not been added to your path
What should I do now?
