I hope this is the right place for this issue report. Currently, all builds for archlinux that use obs_scm fail with the error in the title. Bellow, I copied the build log from the official obs-service-tar_scm package in openSUSE:Tools and the required package is installed python2-yaml.

After some digging, I think I found the problem. obs-service-tar_scm pulls obs-service-recompress as a dependency that according to its PKGBUILD file, depends solely on python (it's python3 on archlinux). So, pacman installs python and python2.

This causes the problem. When there are both versions of python installed (2 & 3) then when building this package I get shebang for python3, #!/usr/bin/python3 in file /usr/lib/obs/service/tar_scm.

I solved this problem by updating obs-service-recompress PKGBUILD file and replacing python in depends with depends=('bzip2' 'gzip' 'xz'). This dependency was weird in the first place for archlinux. Packages for other distros don't depend on python.
