I actually manage to "solve" it. It turns out that the solution was simply to bring up Seahorse (Found under Applications->Acessories->Passwords and Encryption Keys) and in that application open the Preferences. There is a tab shown as "Passphrase Cache", in that tab, activate the second alternative "Cache passphrase for __ minutes". FIll in how long your maximum caching should be and save.
After doing this, passphrase caching started working in both Thunderbird/Enigmail and in Evolution. -- Enigmail does not cache passphrase anymore https://bugs.launchpad.net/bugs/156561 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
