Symbol Lookup Error in Dolphin 2026.04

Since I updated Dolphin to 2026.04 (as part of a general Manjaro update), I can no longer launch the Dolphin file manager. Every time I do so, I get the following error:

/usr/bin/dolphin: symbol lookup error: /usr/lib/libdolphinprivate.so.6: undefined symbol: _ZN19KCoreConfigSkeleton9setConfigESt10unique_ptrI7KConfigSt14default_deleteIS1_EE

Has anyone else encountered the above error, or know any workarounds?

That’s a packaging issue of your distribution.
It didn’t update kde framework kconfig package or something like this.

Actually, that was exactly what was wrong. I apparently had kconfig-git-6.16 installed, but installing 6.25 from the regular repositories fixed it.

Thank you, @meven.

Thank you @meven . I had to pin an old version of dolphin because of this same symbol error on Arch. Once I installed kconfig instead of kconfig-git - it worked.
