[ros-users] rosinstall problems on Debian

[Ugo Cupcic]

Hi,

Yes on lenny you get python 2.5 and for this you need python 2.6 at least.

Installing ros on lenny was a bit of a pain (well in our case). If you
uprgade to the latest debian, then it should make your life a LOT easier
with ROS :)

Cheers,

Ugo
