I haven’t changed anything in the package I’m currently trying to build for debian 7 and 8, yet unfortunately the packages aren’t built and I can’t figure out why.
The logs actually shows that the output .deb packages were generated. Lintian is generated afterwards, but there’s nothing indicating that it’s warnings are/should be fatal. There’s probably a bug in obs’s debian build scripts. I’m having the same trouble: my packages are built accordingly to log, but obs reports failure and the logs are similar to yours.
