I have just migrated from existing arch setup.
I use sddm as DM and I cannot login to kde. I have installed base, base devel, runit, sddm-runit, network-manager runit, elogind-runit and dbus-runit and enabled those services.
After entering the password on sddm, I get an error could not sync environment to dbus. please help. Thanks.
Migration is tricky. I would suggest trying to reinstall as many QT/KDE packages as you can and make sure get the ones from Artix's repos and not Arch's repos. There might be some weird mismatch here.
Which method did you use? The wiki's (https://wiki.artixlinux.org/Main/Migration) or fucktheskullofsystemd.sh (https://gist.github.com/artixnous/41f4bde311442aba6a4f5523db921415)?
I suggest you clear your package cache and do a full update from the Artix repos, to make sure you got our packages:
# pacman -Scc
# pacman -Sy base base-devel
# pacman -Su
There was also case with migration when the user had to reinstall all Arch packages by the ones provided by Artix to get system working, I believe it is mentioned in our wiki.
I have followed the wiki but I didn't install anything related to openrc.
I ran pacman -Sl system | grep installed | cut -d" " -f2 | sudo pacman -S -
once again. now it got fixed itself.
