Upgrade your Ubuntu Distro from the Command Line – Server or Desktop

What release / version are you running?

cat /etc/lsb-release


cat /etc/issue

But you knew that already — to upgrade the version of the Ubuntu installation you have is quite simple – just storing it so that I have it somewhere 🙂

sudo apt-get install update-manager-core
sudo do-release-upgrade

And you’re done! Just give it time (about 1 hr on a slow [54kB/s] connection) ! When running it via SSH, a secondary SSH port is opened for you to allow for external remote access should your current SSH session is reset / crashes / fails…

Wash, rinse and repeat!
