I had a system crash and now my Ubuntu runs into low-graphics mode. All the fixes require running commands with
sudo. When I try this I get
sudo: command not found. When I try logging in with
su - I get an error:
Authentication failed. I also tried
sudo -i but that did nothing. I am really stuck here. What can I do?
$ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin $ ls -l /usr/bin/sudo -rwsr-xr-x 1 root root 121144 Feb 28 2013 /usr/bin/sudo -a sudo output : -bash: -a command not found which - a sudo output: /usr/bin/sudo echo foo output: Permission denied
