I agree, this was a very annoying bug as there are no error messages. Keys are just missing, and importing the old pubring.gpg through both Seahorse and Enigmail interfaces doesn't work.
The "bug" also affects Enigmail. There is a nice description here regarding how to export your old pubring.gpg to pubring.kbx, retaining owner trust: http://stackoverflow.com/a/34221494/405682 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to seahorse in Ubuntu. https://bugs.launchpad.net/bugs/1577198 Title: Imported gpg keys do not show up in Seahorse 3.18.0 Status in seahorse package in Ubuntu: Confirmed Bug description: After clean install of Ubuntu-Gnome 16.04 LTS I tried to import all my previous exported gpg keys. Although it seems the keys are imported, they do not show up in seahorse (Passwords and Keys). Also Evolution did not find to proper keys to decrypt messages. It seems however that the keys have been imported under gpg1 in stead of gpg2. This can also be confirmed with the list command (gpg --list- key and gpg2 -- list-keys). Importing all keys by command (gpg2 --import Multiple_Keys.asc) seems to work.
