Not sure to understand what the problem is (but I'm by no mean an *nix expert).

Any help appreciated

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

try "sudo mkdir /stuff"

Just remembered Ubuntu is funky about the root account. It should prompt your for your password (your normal password).

Same problem (running as root btw)

I genuinely think I am out of space - if I do a apt-get update

You would get access denied if it was a permissions issue.
Did you try df -hi?
Wonder what the chances are you ran out of inodes.

Seems I'm out of inodes... not too sure how to solve that though

Bingo.  I'm not sure if expanding the volume group will add inodes.  If not, you would have to move files off there.  If you could create another partition and format with a larger inode set then you can relocate your files there.

You can try this:
resize2fs /dev/mapper/turnkey-root
