So I've been doing lots of stuff with Ubuntu recently, including containers, Virtual Servers AND Virtual Machines ...
And I remember to run: -
sudo apt-get update
but then wonder why my packages don't get ... updated !
It's simple ... I've run the update which effectively refreshes the list of packages available .... but NOT remembered to run the corollary upgrade process: -
sudo apt-get upgrade -y
which actually performs the update ( or, if you will, upgrade to the updated packages )
I can concatenate this: -
sudo apt-get update && sudo apt-get upgrade -y
