Cannot lock '/etc/group' in recovery mode
I've currently booted into recovery mode, because I removed my sole user from admin :/
When I run adduser oadams admin, I get gpasswd: cannot lock /etc/group; try again later.
For what it's worth, ls /etc/ | grep "lock", returns only mtab.fuselock, so there's nothing to delete.
How can I get my user back in the admin group?
Solution 1:
Check that you are root
whoami
Check that the root partition is mounted read-write
cat /proc/mounts
If you see that your partition is mounted as ro (read-only), try remounting it as rw
mount -o remount,rw /
