It appears i've used 100% of /dev/sda7,does anyone know how i might go about cleaning it up or emptying it out, being that, since learning this, i've restarted my computer, and am now unable to log into the administrator account shown above. since then i've successfully logged into the guest account and:
guest-ihp062@d-Satellite-C655:~$ sudo chmod 755 /dev/sda7 -R
sudo: unable to change to sudoers gid: Operation not permitted
guest-ihp062@d-Satellite-C655:~$ sudo apt-get autoclean
sudo: unable to change to sudoers gid: Operation not permitted
guest-ihp062@d-Satellite-C655:~$ login d
login: Cannot possibly work without effective root
guest-ihp062@d-Satellite-C655:~$ sudo passwd root
sudo: unable to change to sudoers gid: Operation not permitted
What am i missing?
