SUMMARY STEPS TO REPRODUCE 1. Open Dolphin 2. Type nfs:// in location bar, or nfs://server_name:2049 3. Dolphin displays error: “Invalid protocol ” OBSERVED RESULT NFS shares cannot be accessed with the nfs pseudo protocol. Mounting NFS shares with mount command is working. EXPECTED RESULT Direct access to NFS shares from Dolphin. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE NEON useredition (available in About System) KDE Plasma Version: 5.19.0 KDE Frameworks Version: 5.70.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION This problem occurs since the KDE application to 20.04. It seems that the requested library nfs.so is no longer in the KDE NEON package kio-extra.
After rebuilding packages kio-extras and kio-extras-data it works again. 1. get source package from Neon repository: apt source kio-extra 2. install build dependencies : apt install libssl-dev libssh-dev libidn11-dev libpcre3-dev libgtk2.0-dev libmysqlclient-dev libpq-dev libsvn-dev firebird-dev libmemcached-dev libgpg-error-dev libgcrypt11-dev libgcrypt20-dev libtirpc-dev I guess that libtirpc-dev was a missing dependency 3. rebuild the packages with dpkg-buildpackage and install
Sorry the build dependency list in previous comment is completely wrong :/. libtirpc-dev was indeed a missing build dependency.
