I have a few not trusted root certificates in Kleopatra that I would like to change to trusted. The problem is that the relevant option in the 'Certificates' menu is grayed out. Now, I've been looking arround and it seems that the option "Allow clients to mark keys as 'trusted'" in the 'GPG Agent' tab of the 'GnuPG System' section of the Kleopatra configuration should be enabled. Unfortunately, I have this option checked and still I am not able to change the trust status of the root certificates. The Kleopatra self-test results show 'gpg-agent connectivity' to be fine.
Anybody knows what I am missing?
Thanks for your help.
