OK so, I figured out more or less what was wrong. The first time I created the PGP Key, I didn't specify a password (I wanted to check what would happen). It instantly displayed "general error". Then, my subsequent tries triggered the issue that is specified above.
When I tried to create the key via the terminal (as it didn't work with seahorse), here is what was displayed at the end of the process : gpg: fatal: /home/sandra/.gnupg/trustdb.gpg: base de confiance invalide Actually, some bad data had been stored the first time even though the process had failed. I had deleted by hand "pubring.gpg" because I had noticed some data had been stored there, but I should have deleted the entire directory as well. Anyway, there's a bug somewhere. Any idea where I should report it ? -- Seahorse will not generate a key https://bugs.launchpad.net/bugs/321287 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
