Enigmail on Thunderbird requires Gnupg2¶

Enigmail on Thunderbird complains these days that it will soon require Gnupg version 2.

It’s probably not a good idea to deinstall Gnupg version 1 on Ubuntu 14.04 as that would remove a lot of other packages as well. Instead I just installed version 2 additionally:

sudo apt-get install gnupg2

That’s it! Enigmail found that new version automatically.
