version mismatch for hydro #232

Closed YoheiKakiuchi closed 6 years ago

YoheiKakiuchi commented 6 years ago

In ubuntu precise ( 12.04 ), python-catkin-pkg-modules depends python whose version is more than 2.7.5. But version of python is 2.7.3. Then, dependancy of python-catkin-pkg-modules can't be resolved. Where is the version of dependancy set?

Thanks for reporting the problem. Since Precise is EOL we don't test anything on that platform.

I think the problem comes from using the toolchain on Bionic to build the Debian packages. We use stdeb which at the end will invoke dh_python2. I guess the python:any version is defined based on the oldest version of Python on any non-EOL platform.

The same problem exists for the "modules" packages of rosdistro and rospkg.

We released new versions of the affected Python packages using the Xenial toolchain (which doesn't contain that "higher" version dependency):

This will likely be the last release of these Python packages targeting Precise (et al). I created PRs to these repos removing Ubuntu distros older than Trusty.

@YoheiKakiuchi Please comment here if these versions work successfully for you to make sure it does before stopping support for the platform.

@dirk-thomas Thanks a lot

1.1.7 will address this.

It turns our using the toolchain on Xenial is not a guarantee to get the "right" dependency. :disappointed:

Problem fixed Thanks
