I have the same problem too. My environment is Host: Pine64 Pinebook pro, OS:Manjaro ARM Linux aarch64, Kernel: 5.16.15-2-MANJARO-ARM, DE: Plasms 5.24.3 .
After updating the other day, Kmail will not start. To be exact, it crashes right after it tries to start.
When I try to start kmail with CLI, the following message appears and I cannot start it.
kmail: error while loading shared libraries: libqgpgme.so.7: cannot open shared object file: No such file or directory
Thanks!
