I would like to know how to upgrade from my current version of Ubuntu to the next stable from the Command line interface?
You'll first need to make sure update-manager-core is present (it may already be installed):
sudo apt-get install update-manager-core
You may need to check
/etc/update-manager/release-upgrades and change the line:
for the release to show up.
If you run the command
sudo do-release-upgrade -d through SSH then use a GNU Screen, because the upgrade process will turn off SSH -> close the default port and open a new one (it will inform you of this new port), so:
$ ssh USER@HOST $ screen -S upgrade $ sudo do-release-upgrade -d
open a new terminal on client computer:
$ ssh -p PORT USER@HOST $ screen -d $ screen -r upgrade
You can do
for command line updating
(This is actually the same as for Ubuntu Server)
