Subject: digital-ocean-environment-type fails
Date: Mon, 18 Oct 2021 20:40:47 +0100

I've done some more digging. There are various issues with the script
that actually converts the Debian 9 Droplet to Guix.

1. The SSL certificates of gnu.org fail on Debian 9 (since end of Sep).
This appears to be related to a change in LetsEncrypt root certificates
2. The guix binary used is rather old

I don't have time to submit a merge request now. I have adapted the
included script to work on Debian 9 (uncomment 1x line), 11 and Ubuntu
21.04. This should be good until the bug has been resolved.

```
#!/bin/bash

# Guix 1.3.0 on DigitalOcean
# Convert Debian 11 or Ubuntu 21.04
