Really am stuck here. I have scoured the net and this seems a fairly common issue pointing to root space. On start up everything seems fine and i get to my users log in page with the 2 users names. However in the bottom right corner is the message in the title. If i log in it just refreshes and goes back to the same log in page.
I have pressed ctrl alt F1 as per the posts and logged in with the IT password set on this pc. However when i enter sudo apt-get clean the system then asks me for a sudo password.
As far as we are aware there is no sudo password on this pc and if there was there are only 3 passwords i ever use and none of them work. I can run other sudo commands however it does not ask me for a password. I have also run the df -h and it looks like i am at 100% as per others posts. Can anyone suggest how i can get around the sudo password or clean up space another way?
