I’m not an expert on Linux by any means, but figured I’d better install them, about 400MB worth. Guess which program didn’t update? Yep, Update Manager. It was suppose to be the latest version 4.8.4.
I opened up a terminal window and this did the job via command line:
sudo apt-get update # Fetches the list of available updates sudo apt-get upgrade # Strictly upgrades the current packages sudo apt-get dist-upgrade # Installs updates (new ones)
Remember that you need to enter your super-secret password after each sudo command. I also used the default for any install errors.
