Were you also curious (or desperate) to try the latest and greatest testing or internal development edition of KDE Neon, changed your mind, tried to switch back to the "user" edition just to realize that all these brand new packages cannot be easily downgraded?
The newer packages linger around and can cause crashes and inconsistencies when mixed with older versions in the stable edition.
This script helps you with downgrading all KDE Neon packages to the latest version that is available in the enabled KDE Neon repository.
This is something you need to do by hand first. Edit the file /etc/apt/sources.list.d/neon.list and switch to your desired edition.
For example:
Replace http://archive.neon.kde.org/testing/ with http://archive.neon.kde.org/user/
Run the following for downloading and executing the script in one go:
bash <(curl -s https://raw.githubusercontent.com/tiguchi/kde-neon-downgrade/master/kde-neon-downgrade.sh)
- The script creates a list of all packages that are newer than the latest known version in all active package repositories
- For each of these packages it then determines the latest available version and whether these originate from the KDE Neon package repository
- Manually installed newer packages that are not provided by the KDE Neon repository will be ignored
- In the end it runs
apt-get installfor all of these KDE Neon packages, specifying the correct available version number
