I'm on Debian as well and the Ubuntu .debs work most of the time
(snapshots.debian.org and a Ubuntu source helps ;) ).
Regarding the ROS source packages, they seem to be hand crafted instead
of relaying on the nice Debian build system. I've talked to Vincent
about this some days ago and he mentioned that ROS2 will probably use
the CPack system fromn CMake which is just es broken :/. Maybe we can
convince them together to go with debhelper, as it would be a necessity
to get it into Debian or Ubuntu anyhow and ease up a lot of things.
