Lintian tag: python2-script-but-no-python2-dep

Type: error

Description (from lintian-explain-tags)

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.
