And I seem to have solved the issue: https://build.opensuse.org/package/show/home:ojkastl_buildservice:Branch_server_monitoring/golang-github-prometheus-prometheus Revision 6 added the pieces. Revision 7 added a PACKAGING_README.md, that contains the steps necessary to create the tarball locally, outside of OBS. The package is working with the latest promu version. Turns out the error was not caused by promu, but by missing things aka the assets for the UI. Witek, can you test the package, please? If it works, can you please test the instructions for creating the tarball locally? Kind Regards Johannes
