Upgrade from 5.6 to 6

[Moltke]

Hello  :dft010:!

I'd like to update my release of linux lite to the last version
my version is actually the 5.6
is it possible to do it from the shell in commands lines ?


Thanks to you for your advices

Yes, and no. Officially, there's no support for upgrades from one series to the next, i.e. 5 to 6. The recommended way is to do a fresh install. That being said, you can try this:

Backup your system before doing that with timeshift is recommended, should anything go wrong, you can get it back the way it was.
