I tried to update KaOS 6 in the last few days but I was not able due to a dependencies error.
Pacman reported an error about a package (kpm* or kmp*, I don't remember the exact name) update to the kde-next version would break the calamares dependecies.
I tried to update it for few days, but I always get the same error. I solved the problem removing the calamares6 package and the update run fine.
I'm not sure if it's a bug or not and if you're aware of it, I'm just reporting it for your information.
