ubuntu 16.04 LTS When I started my computer my admin acct was gone, now there is only a guest login. Cannot change user either. When I check user accts it only shows the guest acct. I tried this:
guest-4xiaqd@user-HP-Pavilion-dv7-Notebook-PC:~$ adduser louise
adduser: Only root may add a user or group to the system.
guest-4xiaqd@user-HP-Pavilion-dv7-Notebook-PC:~$ adduser
adduser: Only root may add a user or group to the system.
guest-4xiaqd@user-HP-Pavilion-dv7-Notebook-PC:~$
guest-4xiaqd@user-HP-Pavilion-dv7-Notebook-PC:~$ sudo adduser louise
sudo: unable to change to root gid: Operation not permitted
sudo: unable to initialize policy plugin
I didnt change any settings, only logged out and turned it off.
Any answers will need to be very specific because I do not understand what I am doing.
Thanks, everyone.
