Comment 1 Akseli Lahtinen 2024-02-13 09:44:12 UTC 
Updating works with following command:

sudo apt update && sudo apt dist-upgrade -o DPkg::options::="--force-overwrite"
Comment 2 Akseli Lahtinen 2024-02-13 12:21:32 UTC 
Going through the packages one-by-one to find all broken ones:

kf6-baloo
kf6-baloowidgets
kf6-plasma5support
kwin-common
libkpimgapi5-data


I found these by piping the force-override dist upgrade to a log file and then listing anything that raises a dpkg: warning

Comment 4 Jonathan Riddell 2024-02-19 09:47:54 UTC 
This isn't supported by us but there's obviously demand so maybe we should work out how.

The problem is files moves around in unstable first and then there are clashes with testing and user editions on upgrades.

I think to do it we need to just advise to turn on force-overwrite

`echo force-overwrite > /etc/dpkg/dpkg.cfg.d/neon-edition-change`
