Cannot build devel or master using Docker
Hey there,

Attempting to help out the folks at MAGIC build this via Docker, and seems there is something broken right now. I already tried using devel instead of master after reading https://github.com/moneroexamples/onion-monero-blockchain-explorer/issues/317, but even though I now get much further I'm still running into issues.

I've tried with both the existing Dockerfile (which uses `ubuntu:20.04` as the base) and a slightly altered version that uses `ubuntu:latest` instead to see if an updated toolchain would resolve the issue.

**On the existing Dockerfile:**
