Question

Seemingly unable to install older version of Mono. Why/How?

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/4.8.1.0 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.

Hi there @orbitstorm88,

Once you make the change to the repository list, you need to run sudo apt update and then run the sudo apt install mono-complete.

Let me know how it goes. Regards, Bobby
