python2-script-but-no-python2-dep

Packages with Python2 scripts should depend on the package python2. Those with scripts that specify a specific version of Python2 must depend, recommend or suggest on that version of Python2 (exactly).

For example, if a script in the package uses #!/usr/bin/python2, the package needs a dependency on python2. If a script uses #!/usr/bin/python2.7, the package needs a dependency on python2.7. A dependency on python (>= 2.7) is not correct, since later versions of Python2 may not provide the /usr/bin/python2.7 binary.

If you are using debhelper, adding ${python2:Depends} to the Depends field and ensuring dh_python2 is run during the build should take care of adding the correct dependency.

In some cases a weaker relationship, such as Suggests or Recommends, will be more appropriate.
