SUMMARY When opening "kcmshell5 user_manager", no existing users are shown. Nothing happens when pressing the + button to add a new user. STEPS TO REPRODUCE 1. Get a Musl system like Gentoo or Alpine Linux 2. Run "kcmshell5 user_manager" OBSERVED RESULT No existing users aren't shown and new ones can't be added as nothing happens when pressing the + button. Nothing appears in the CLI either. EXPECTED RESULT Existing users to be shown and possible to be modified, and the possibility to add a new user or remove one. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Linux 4.19.69 KDE Plasma Version: 5.16.5 KDE Frameworks Version: 5.61.0 Qt Version: 5.12.4 ADDITIONAL INFORMATION This system (Alpine Linux) uses Musl so this issue is probably because of that.
Do you have AccountsService (https://www.freedesktop.org/wiki/Software/AccountsService/) installed?
Status fix.
I'm... Embarrassed to say I did not and installing it fixed the issue... The joys of packaging I guess, I never saw anywhere this was needed. Thanks for the solution!
