I can't log in into my Ubuntu 20.04 VM. The title contains all the relevant information.
I am 100% sure that I used the correct password because I created the VM multiple times with the same password and tried to login multiple times each time and always have the same issue.
First, I had automatic login enabled. When I tried to change the password to the password that I thought was the correct password, it told me that the new and old password must not be equal. Then it asked me to enter the old password for permission and when I entered it, I got an error message telling me it didn't work.
Later, I chose to disable automatic login because I read that it may solve the issue but nothing changed.
I read many posts where people had the problem that their password has been submitted before they could enter it that got the same error message or people that got another error message with their correct password but I did not found a post where someone got the same error message that I got who actually used their correct password.
I also checked whether I accidentally enter anything before I enter the actual password, but that is not the problem either.
Is there anyone that knows how to solve this?
