I gathered that libssl1.0-dev is required but newer Ubuntu releases don't provide it at all. Is there a solution to that problem?

same issue on Debian 10 (Buster).

We're linked against an outdated and likely broken version of OpenSSL. Newer versions substantially changed the APIs we call for BigNumber operations, and frankly I don't have time to fix it.

However, all hope is not lost. I run by using Docker and docker-nvidia with the Dockerfile contributed by nexus166:

# docker build -t scallion -f Dockerfile.nvidia .
# docker run --runtime=nvidia -ti --rm scallion --listdevices

Leaving this open so people find it if they glance at issues.

This unfortunately doesn't work for me, as my GPU is not Nvidia..

..And I can confirm the build does not work with an AMD Radeon RX 5700 XT. But at least I learned how to do a Docker build and then delete Docker images on Ubuntu 20.10. Turns out you need the entire git clone and not just the Dockerfile.nvidia file, also that dangling period at the end of the first docker build line needs to be in there. I wonder how much of a $$donation would be needed to get that OpenSSL API working...:P Sandy
