[ros-users] Error installing ROS in Debian

Hi all,



We are trying to install ROS in a Debian distro from svn following the
Ubuntu/Linux instructions provided in the web-site. We have a
squeeze/sid version of Debian, which can be seen in /etc/debian_version.
However, we get a weird error:



[ rosmake ] rosdep install failed: Could not detect OS, tried
['uninitialized from ROS_OS_OVERRIDE=name:version', 'rosdep_test_os',
'debian', 'ubuntu', 'ubuntu', 'fedora', 'rhel', 'arch', 'macports',
'gentoo', 'cygwin']

Traceback (most recent call last):

File "./rosinstall", line 326, in <module>

    sys.exit(rosinstall_main(sys.argv) or 0)

File "./rosinstall", line 319, in rosinstall_main

    subprocess.check_call("source %s && rosmake rostest
--rosdep-install" % (os.path.join(options.path, 'setup.sh')),
shell=True, executable='/bin/bash')

File "/usr/lib/python2.5/subprocess.py", line 462, in check_call

    raise CalledProcessError(retcode, cmd)

subprocess.CalledProcessError: Command 'source
/home/treaccio/tmp/ros/setup.sh && rosmake rostest --rosdep-install'
returned non-zero exit status 255



Looking at the error we also tried to assign
ROS_OS_OVERRIDE=debian:squeeze/sid manually, using the export command,
before running rosinstall. But this also output an error:



Using environment variable ROS_OS_OVERRIDE=name:version

[ rosmake ] Detected rosout not built, adding it to the build

We realized that ROS uses its own tools for Python to detect the
underlying OS. For some reasons, that tool doesn't work for us. Are we
missing anything? Is there any special issue we need to take into
account for Debian installation?



Thanks in advance!
