Add python-modbus-pip to python.yaml

[tgaspar]

Please add the python-modbus-pip dependency to the rosdep database.

Package name:

python-modbus-pip

Package Upstream Source:

Link to source repository: https://github.com/riptideio/pymodbus

Purpose of using this:

There already is an entry for python-modbus in the YAML. However, the Ubuntu and Debian repositories have outdated versions, 1.3.2 and 1.2.0 respectively.

When installing from PyPI we get a more recent version - 2.5.3.

I suggest to keep the outdated python-modbus inside the YAML to not break compatibility.

One last change, since these are identical please make the python3- key an alias to the python- key.

python-pymodbus-pip: &migrate_eol_2027_04_30_python3_pymodbus_pip
  debian:
    pip:
      packages: [pymodbus]
  ubuntu:
    pip:
      packages: [pymodbus]
...
python3-pymodbus-pip: *migrate_eol_2027_04_30_python3_pymodbus_pip

Ok, will do! Quick question though: how do I determine the EOL? Or better, how did you determine it?

how do I determine the EOL? Or better, how did you determine it?

I know we're transitioning to Ubuntu Jammy for ROS Rolling at the moment, so I assumed both that it counts as a supported platform and that it has the furthest away EOL date of April 2027.

I could use a little help here. I am not sure why I am getting the following nosetest error:

Package 'python-pymodbus' could not be found for ubuntu focal on amd64

and

Package 'python-pymodbus' could not be found for ubuntu jammy on amd64
Mostly because these are the lines of the YAML that remained untouched by my PR.

@tgaspar the PR checker sometimes checks more lines than needed (see #31439).
We will need to fix the python-pymodbus entry in another PR and rebase this one (or you can also fix that here).

[ivanpauno]

To be more clear, this probably fixes the issue:

python-pymodbus:
  debian: [python-pymodbus]
  ubuntu:
    '*': [python-pymodbus]
    jammy: null

[tgaspar]

@ivanpauno thanks for the suggestion. Given the errors I received before I added both jammy and focal. Hope that's fine ...
