Hi

Is it possible to switch from the Developer stable version of Neon to the User stable version without a reinstall?

Cheers.

IMHO if it could be done it would involve manually downgrading almost every kde related package

You're probably right.
I haven't turned on this Neon box for several weeks and there are hundreds of updates waiting.
I wondered if swapping the repos to the user branch would eventually catch up and then supersede what is currently installed.

Not sure if this is still relevant to you, but I just managed to do it in a test virtual machine.

You need to edit the file /etc/apt/sources.list.d/kde-neon.list
and point it to the user's version

Code: Select all


deb http://archive.neon.kde.org/user/ xenial main
# deb-src http://archive.neon.kde.org/user/ xenial main


and also create a file in etc/apt/preferences.d/ with the following contents

Code: Select all


Package: *
Pin: release o=neon
Pin-Priority: 1300

After that a

Code: Select all


sudo apt update
sudo apt full-upgrade

should revert everything to kde neon's user version except a couple of packages or so that can be easily downgraded the manual way.

Seemed to work in the testing environment I tried, but don't blame me if your PC catches fire after following these instructions

I know it's an old topic, but I ran into the exact same problem today. I was using the `testing` edition for the past month and ran into too many problems. A switch back to the `user` edition really requires a reinstall of all affected KDE Neon packages while specifying the correct version numbers from the user edition repository.

I was too lazy to do that by hand, and created a Bash script instead that does it automatically: https://github.com/tiguchi/kde-neon-downgrade

I hope someone else in the same situation will find it useful. The only thing that needs to be done by hand before running my script is to edit the `/etc/apt/sources.list.d/neon.list` file back to the desired edition (e.g. `user`).
