Due to pcs depending on openwsman, and openwsman is not at the moment ported to openssl 1.1.0, pcs cannot be built from sources in rawhide.
As far as I know pcs does not depend on openwsman. When I try to scratch-build pcs from sources for current rawhide, I get this error:
ERROR: Command failed:

Is openwsman-python3 a new dependency of some dependency of pcs?
openwsman has been fixed and I initiated a build for pcs, however now the tests fail.
Tests have been fixed and pcs now builds just fine.
Thank Adam Williamson very much for digging into this.
