BYOC instructions mention "The following instructions are for Ubuntu 18.04." which has been EOL for some time

The https://www.appveyor.com/downloads/appveyor/appveyor-host-agent.deb also works on Ubuntu 20.04, but that is EOL now as well.

The application fails on Ubuntu 22.04 or later because it depends on EOLed libssl1:

root@77efc0303438:/opt/appveyor/host-agent# ./appveyor-host-agent
...
No usable version of libssl was found
Aborted (core dumped)

The embedded .NET runtime appears to be version 3.1, but even trying to use the packages from Microsoft doesn't work because of the same libssl dependency:

root@77efc0303438:~# curl -sSL https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb -o packages-microsoft-prod.deb
root@77efc0303438:~# apt install ./packages-microsoft-prod.deb
...
root@77efc0303438:~# apt update
root@77efc0303438:/opt/appveyor/host-agent# apt install dotnet-runtime-3.1

All of the above works OK on Ubuntu 20.04, but since deadsnakes PPA dropped support for 20.04. It's more difficult to use different Python versions on a 20.04 based system. pyenv works as a workaround.

Is there a version of appveyor-host-agent app using a more recent .NET runtime available?
