Your Manjaro repos have nothing to do with where you get visual things for Plasma. I am able to download Bonny-Dark-Icons without issue, so it doesn’t seem that Pling is down. Are you able to connect to pling.com and store.kde.org ?
Yes, the web pages work fine. Thinking about that it’s not in the repos, I recently installed Portmaster (from the repos). Got rid of ads in the Web Browser widget that way on my second Activity. Hm, maybe that’s blocking the connection… Yepp, stupid me. Portmaster ran in the background.
How about deleting the thread or maybe renaming it to something more useful for others now.
Thanks for replying, it was a big hint for me
