I’m attempting to install an older version of mono with Ubuntu 20.04 as the application I’d like to host is not yet C# 7.0 compliant. I’ve followed dozens of tutorials with constant droplet rebuilds and I’m at my wit’s end with this.
Using the steps provided at mono-project[dot]com/download, I changed the repo link from the standard
stable-focal main to
wheezy/snapshots/184.108.40.206 main and that appears to work as I’ve confirmed that the link saved in
/etc/apt/sources.list.d/mono-official-stable.list is correct.
The moment I run
sudo apt install mono-complete however, something pushes the latest version of Mono instead. A coworker tested this briefly with Lightsail and had no issues so this appears to be something with Digital Ocean specifically.
