SUMMARY STEPS TO REPRODUCE 1. Encrypt a file in Kubuntu 19.10 with a right click in dolphin on the file 2. Upgrade to 20.04 3. right click on the encrypted file OBSERVED RESULT The encryption and decryption menu is missing EXPECTED RESULT The encryption and decryption menu is shown as in 19.10 SOFTWARE/OS VERSIONS Linux/KDE Plasma: Dolphin Version 19.12.3 (German version) ADDITIONAL INFORMATION When trying to install the dolphin service "Decrypt and Extract Here Service Menu" the result is "Installation des Dolphin-Dienstmenüs fehlgeschlagen "
This will probably require a change on the side of the service menu - there's most likely nothing we can fix on the Dolphin side. Given that the author of "Decrypt and Extract Here" hasn't been active for over a decade (it's quite a miracle that it worked until now!), I suspect that someone else will have to update the service menu.
Yeah, this service menu comes from kgpg, and I suspect it got dropped in Kubuntu 20.04 due to lack of development.
