Plasma Software Center: Unable to load applications.

Archer1X · 2020-02-06 11:14:52

I just installed a fresh ISO with KDE Plasma.

When I opened the Discover Software Center, it threw this error:

Unable to load applications. Please verify Internet connectivity.

My internet is working just fine. I have also read several threads that mentioned the same error but no solution that been provided
solved this problem. I have installed packagekit-qt5, fwupd, flatpak, to no avail.

Anybody here have the same problem?

What did you guys do to solve it?

These were the errors after I try to launch it from terminal:

Do you have ksysguard and libksysguard packages installed? What's the output of command 'pacman -Ss plasma | grep instal' ?

V1del · 2020-02-06 13:03:02

Is your session alright? How do you login and start plasma? What are your outputs for

loginctl session-status
printenv | grep DBUS
hostnamectl

I logged in and start the session using startx/xinitrc.
These are the output:
