I've had problems accessing internet so I rebooted my computer. However, after the reboot, I could only log in in a commandline kind of manner, the GUI is gone.
I typed df -Th, which returns:

I tried deleting some files with rm and sudo rm but an error occurs saying filesystem is in only accessible in read mode. I tried chmod +x with the same error.
I tried mount -t tmpfs -o mode=1777 /tmp in sudo mode (suggested here: no-gui-disk-full-broken-system-after-updating-sources), reply:
mount: can't find /tmp in /etc/fstab
When I try startx, the first lines go too quickly for me to read but I get those error lines at the end of the output:
Fatal server error: Could not create lock file in /tmp/.tx0-lock
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error
xauth: error in locking authority file /home/name/.Xauthority
When trying sudo apt-get update, the computer cannot resolve security.ubuntu.com, extras.ubuntu.com, archive.canonical.com and fr.archive.ubuntu.com.
Am I using too much disk space for the GUI? Any idea how I can fix this?
