package signing

Hello, I'm using a local obs server and got a problem with package signing. I tried this guideline https://en.opensuse.org/openSUSE:Build_Service_Signer, but it's outdated and after a few workarounds like coping files from ~/.gnupg/* to /srv/obs/gnupg/ got this message [11882] signer exiting... [12254] signer started waiting for an event... signing x86_64/*** 127.0.0.1: Connection refused sign failed: 256 - checking digest /srv/obs/jobs/x86_64/***.src.rpm: digests OK sign failed: sign /srv/obs/jobs/x86_64/***src.rpm failed sign -k returning key perfectly also, I tried to use obs_admin --update-project-signing-key project ./key.pgp.pub ./_signkey and got error no secret key BR, Ivan
