I successfully installed Ubuntu 12.04.
Then, at the moment I need to install the updates, I get this message:
NOT ENOUGH FREE DISK SPACE
THE UPGRADE NEEDS A TOTAL OF 449M FREE SPACE ON DISK '/'.
PLEASE FREE AT LEAST ADDITIONAL 425M OF DISK SPACE ON '/'.
EMPTY YOUR TRASH AND REMOVE TEMPORARY PACKAGES OF FORMER INSTALLATIONS USING 'SUDO APT-GET CLEAN'.
I made sure I had plenty of space before installing Ubuntu.
The Trash is empty.
I try opening Terminal but when I click on it, nothing happens. I cannot input
sudo apt-get clean.
Please help me. I want to upgrade to 12.10.
