A mountpoint is the directory that a partition appears as when mounted. If you mount the root partition using the GUI in the live system it will be something like `/run/media/ubuntu/root`. If you open a file manager window on it, you can drag it's icon to the terminal window to paste the path into the command line. You can also check by looking at the output of running `mount` (with no arguments). The mounted device will most likely be `/dev/sda1` or `/dev/sda2` and the mountpoint will be the directory name that follows the word "on". So look for line that begins with `/dev/sda` something. The commands you run will then be something like:
sudo apt-get -o RootDir=/run/media/ubuntu/root update sudo apt-get -o RootDir=/run/media/ubuntu/root dist-upgrade I recommend trying this before trying to update to an entirely newer version of the OS. If you get the wrong partition mounted (eg if you have a separate boot partition) `apt-get` will complain and not do anything.
