Even if automated, you may need a "revert to manual" process if automation breaks (for whatever reason).
Some points:
- The /etc directory is your friend in all this
- cat /etc/os-release - needs to be done before and after to check the release has been complete
- You should upgrade regularly - not least because you need to get the latest security updates
To ensure the upgrade can happen successfully you need to check/edit the release-upgrades file.
sudo emacs -rv /etc/update-manager/release-upgrades
Change Prompt=never to Prompt=LTS (the latter checks to see if a new LTS release is available).
Useful commands:
- sudo apt update
- sudo apt full-upgrade
- sudo do-release upgrade
Don't forget to check os-release for successful install.
