Hi, I have pushed a commit to this package: https://build.opensuse.org/package/show/multimedia:apps/upmpdcli The web interface reports: Files could not be expanded: service error: bad link: conflict in file upmpdcli.spec I have no idea how this error happened and how to fix it. I just modified like 2 lines in upmpdcli.spec. Any help ?
