Created attachment 169307 [details] Error message when trying to connect to NFS SUMMARY I set up several NFS connections to my home server in Dolphin using Fedora 39 (and Plasma 5.27.1 If I recall correctly). On Fedora 39 I could always access my NFS shares via the bookmarks or by typing `nfs://192.168.2.202/export/music/` on the location bar. After updating to Fedora 40 (Plasma 6) I can no longer access my NFS shares via the bookmarks nor via the location bar and I get the following error message: "Unable to create KIO worker. Unknown protocol 'nfs'." STEPS TO REPRODUCE 1. Set up a connection to a NFS share in Fedora KDE 39 (and Plasma 5.27.1 If I recall correctly) by typing `nfs://IP.ADRESS` on the location bar of Dolphin. Dolphin connects to the NFS share. OPTIONAL: save this connection as bookmark on the Places panel 2. Update to Fedora KDE 40 using `sudo dnf system-upgrade download --releasever=40` as recommended in https://docs.fedoraproject.org/en-US/quick-docs/upgrading-fedora-offline/#sect-performing-system-upgrade 3. Try to connect to the same NFS share as in step 1, either via bookmark or by typing `nfs://IP.ADRESS` on the location bar of Dolphin. OBSERVED RESULT Dolphin fails to connect to the NFS share and returns the following error message: "Unable to create KIO worker. Unknown protocol 'nfs'." EXPECTED RESULT Dolphin connect to the NFS share. SOFTWARE/OS VERSIONS Linux: Fedora 40 KDE Spin KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0
The nfs worker for KIO was removed from KF6, which Plasma 6 is based on, due to issues with porting. There is some (currently stalled) work going on to port nfs support to KF6 here: https://invent.kde.org/network/kio-extras/-/merge_requests/343 You should still be able to access your nfs shares by mounting them directly, rather than through KIO.
