I have a few Raspberry Pi at home, they’re used for specific purposes such as Kodi media player, Pi-hole server, and a backup DNS/DHCP server. Recently, I need to turn on the backup DNS/DHCP server, which is one of the Raspberry Pi devices running Arch Linux.

When I run Dolphin, there is an annoying error message “Could ont enter folder tags:/”. Though it doesn’t cause any problems, it’s very annoying.
