I've been trying to load a p12 file into Kleopatra using Q4OS Aquarius, and Andromeda. I wasn't able to load the p12 into Aquarius at all. In Andromeda, I can load the certificate into Kleopatra, but once it's there, I can't decrypt received email messages in KMail. It throws an error when I enter the protection password for the certificate, then press okay.
Something else I noticed, is there seems to be a status bar on the lower right hand side of the Kleopatra user interface. It seems to indicate a partially completed task at all times.
I've mostly used Kleopatra Version 4.0.0.241203 (24.12.3) under Debian Trixie, so I'm still getting familiar with the version in Trinity.
Any tips on some more things I could check? I've started tdepim issue for this:
https://mirror.git.trinitydesktop.org/gitea/TDE/tdepim/issues/169
I don't know if there is some kind of missing user knowledge, or perhaps a workaround for this issue. I'd be happy to add some more updates to issue 169 if that helps in the troubleshooting.
TIA,
