If I remove the install lines for /usr/bin and /usr/share/applications, or don't do a mkdir for them, my result is:
install: target '/var/ypkg-root/root/OmegaT/install/usr/bin/' is not a directory: No such file or directory
I've read the install manpage about a thousand times, and been googling, and I still have no idea what it is you're getting at.
Any chance somebody else can grab my package.yml and build this locally, and see if their git format-patch results in something that is importable?
I have no idea what's going on here, but I've tried everything I can think of, and everytime I do a git am, I end up with a non-appliable 0001-disable_win_mac.patch
Landed in unstable after a few tweaks:
Note that I made the package name lowercase to match the Git repo.
