I am trying to log in to an old desktop i used over a year ago, using lubuntu. i remembered the password to decrypt it but i forgot the login password.
I have looked about and i was able to get into grub screen, i got to recovery menu and i changed it with "passwd username" confirmed changing of the password.
It said it was changed successfully, however when i try to log in, it doesn't say the password is wrong like all other wrong attempts, instead the screen goes dark for few seconds as if it's loading, but then the login screen reappears asking for password again.
I then also tried another "drastic" way i read on here using "nano -B /etc/shadow" and removing password so i just need to hit enter at login.
Now when it boots and gets to the login page, it doesn't show a box to enter password, just shows my username and login button, which is great. However when i click login the same thing happens as above....it just reloads the login page.
Please how can i access my account? and why have the above methods not worked for me?
I dont have many details, i believe the verion of lubuntu on the machine is 16.04.1
