From 16.04 LTS to 15.10

[HellForge]

How do i get there from my terminal ?
trying update and dist-upgrade and nothing is working there.
also changed on the "discover" to get "normal" releases also.

If you really mean From 16.04 LTS to 15.10

then you don't.

15.10 is older so you can't 'upgrade' to it from 16.04.

If you do mean 15.10 to 16.04 LTS then:

sudo apt update && sudo apt full-upgrade
sudo do-release-upgrade -d

The first line makes sure you are up to date on your current version. The second does the upgrade.

It is recommended to perform a clean install. In such a case you can run

dpkg --get-selections > /home/YOUR_USER/software.txt

before installing and copy it somewhere safe. After the install and initial update, run the following to install all your software:

sudo apt update
sudo dpkg --set-selections < /home/YOUR_USER/software.txt
sudo apt-get dselect-upgrade

Personally, I've had mixed results with *buntu release upgrades.

no need for '-d' AFAIR

do-release-upgrade -m desktop

worked fine in a wily VM the other day.

Having re-read the help text the -d switch doesn't mean desktop which may explain my mixed results!
