This does not seem to be my day. For some reason (mostly experimenting) I used sudo visudo and removed my name (the whole line) from there. Now, of course, I cannot use sudo any more. I cannot even use "sudo su" to be root. The whole system is unaccessible to me now.
I followed this link:
but I could not use 'sudo visudo' from the root command line. It said root is not in the sudoers file. This incident will be reported.
I don't get this, how can root be not in the sudoers list?
Any solution(s) to this issue?
