I'm not sure where to file this, thus let's start here.
I made evolution available for rpm2flatpak, just as  says.
I successfully 'fedpkg module-build' it , but 'fedpkg flatpak-build' fails .
If I read it properly, then it tries to mix liboauth/libcurl/libssh and fails due to excluded packages. I build liboauth as part of , thus I'd expect it'll work fine, but I do not know how this is supposed to work.
Any hints, please?
By the way, the  shows also other suspicious warning near the top, which is possibly related to the FileNotFoundError later in the log. I do not know how much expected it is.
The problem here is that libssh grew a dependency on libssh-config with the Fedora 30 update to 0.9 and the Fedora runtime needs to be updated to match. (The container install is against the current Fedora repos, but the list of packages to include is based on the runtime.)
I'll look at updating and rebuilding the runtime.
Closing as this was fixed a while back.
