Description of problem: My sigul bridge and server are deployed on CentOS (to reduce OS upgrade frequency), but this only gets sigul-0.101 which seems to be quite behind upstream now. If it were incredibly stable, I wouldn't mind but I find it necessary to frequently restart sigul_server due to broken RPC. If such an upgrade isn't possible for whatever reason, I'd at least like to know that much so I can consider redeploying on Fedora (assuming that'd work). I had started there originally but couldn't make it work at all due to some incompatibility I don't remember the details of.
Sigul v0 series will require GPGv1, which is not available for EL7 or any recent Fedora releases. Sigul v1 works with Python3 and GPGv2(.1+), which means it will work out of the box with EL8 and any recent Fedora release.
