You can try the main repos;

deb https://repo.pureos.net/pureos/ byzantium main

That works. It must be a problem with mirrors.sonic.net.

I'm not sure - it looks like they do have a signed release file here: https://mirrors.sonic.net/pureos/repo/pureos/dists/byzantium/

Switched my sources.list back to the mirrors.sonic.net repositories today, and now it seems to work without any errors.
