I am trying to build a package for ubuntu trusty using sbuild, but few dependencies are available in vivid repo. So, I added the vivid repo with --extra-repository tag with sbuild command. But I am getting the following error with that:
gbp:error: 'sbuild --extra-repository=deb http://ports.ubuntu.com/ubuntu-ports/ vivid main' failed: it exited with 255
Any idea how can I resolve this issue? I need that repo to build packages. TIA.
