In Ubuntu 15.10 when using Mozilla Thunderbird with Enigmail I get the following warning (in Swedish):
Du använder GnuPG version 1.4.18, vilken inte längre stöds. Enigmail kräver GnuPG version 2.0.7 eller senare. Vänligen uppgradera din installation av GnuPG annars fungerar inte Enigmail.
As I understand it my version of GnuPG is to old and I need to upgrade. However, I can't figure out how to do that.
At Enigmail FAQ I read that:
you install GnuPG 2.0 via the regular package management system of your distribution (e.g. apt, yum, yast). On many distributions the package is called "gnupg2" or "gpg2"".
But I'm only a normal user, and I don't understand what that means and what I'm suppose to do.
I would be very happy for some help. For example some kind of very basic step by step ”How to” guide.
