If you are using the Enigmail security add-on for Mozilla Thunderbird under Ubuntu Linux, you may have recently discovered (as I did today) that it no longer works with the version of GnuPG that you have installed, and that you need to upgrade. But it’s not evident how to do this, as there is no GnuPG update available in the Ubuntu Software Center.
Fortunately, there is an easy way to upgrade Ubuntu to GnuPG 2. Just open a terminal and type:
sudo apt-get install gnupg2
and enter your password when prompted.

I have the weiredest of problems. When I do `gpg –version` my system tells me I have `gpg (GnuPG) 1.4.20`
elliot@warmachine ~/Downloads $ gpg –version
gpg (GnuPG) 1.4.20

But when I try to upgrade it tells me I already have the latest version :
elliot@warmachine ~/Downloads $ sudo apt-get install gnupg2

gnupg2 is already the newest version (2.1.11-6ubuntu2).
The following package was automatically installed and is no longer required:
libllvm4.0
Use ‘sudo apt autoremove’ to remove it.

So now I’m so confused. I don’t know where GPG installs itself when you install it (teach me how). But I am unable to fetch my key because when I try to do that, gpg tells me it doesn’t support https.
elliot@warmachine ~/Downloads $ gpg –fetch-keys https://keys.qubes-os.org/keys/qubes-master-signing-key.asc
gpgkeys: protocol `https’ not supported
gpg: no handler for keyserver scheme `https’
gpg: WARNING: unable to fetch URI https://keys.qubes-os.org/keys/qubes-master-signing-key.asc: keyserver error
