Debian 9 (KDE), setting up KGPG.
After importing my private keys, I
tried to set the trust level and KGPG shows a "in-progress" icon turning
forever but without any error message.
Installed Kleopatra and
did the same and this time received and error message "An error occurred
while trying to change the owner trust for Michalng".
System is okay as trust level can be set when performed in konsole.
gpg --edit-key KEY-ID
gpg> trust
5
Startup Kleopatra/KGPG and confirmed that trust status is updated
A second observation :
In dolphin, right click encrypt files selection is available when Kleopatra is installed
In dolphin, right click encrypt files selection is not available when KGPG is installed
