I run Lubuntu on an old laptop I have, that I mostly use for watching films with Kodi. I'm not very used to Debian/Ubuntu flavours, so I'm making lots of notes.
lsb_release -acheck distro release version
When there's a new proper version of the distro things get a little trickier sometimes, especially if you haven't updated in ages.
I ran into a problem where it wouldn't update from 15.10 to 17.10 becaues for some reason it was set to only upgrade to LTS releases (fine), but I was somehow on a non-LTS! This was easy enough to change in
- Getting ready / setting the table:
sudo apt-get updatethen
sudo apt-get upgradethen
sudo apt-get dist-upgradeto get your current version up-to-date.
sudo apt-get autoremoveand
sudo apt-get cleanto clean up a bit.
sudo apt-get install update-manager-coreto make sure update mechanism is up-to-date.
Adding these lines to
/etc/apt/sources.list auto picks the closest mirrors when updating.
