Some time ago I had troubles with my gnupg installation. Namely gpg was unable to read keys from my trusted.db. I figured this had something to do with the upgrade to GnuPG 2.1.0.
cd ~/.gnupg mv pubring.gpg pubring-$USER.gpg mv secring.gpg secring-$USER.gpg mv trustdb.gpg trustdb-$USER.gpg gpg --import pubring-$USER.gpg gpg --import secring-$USER.gpg rm pubring.$USER.gpg secring-$USER.gpg rm trustdb.gpg mv trustdb-cadw.gpg trustdb.gpg
That’s all for now folks and happy new year!
