Tag: python2-script-but-no-python2-dep
Severity: error
Check: scripts
Explanation: Packages with Python2 scripts should depend on the package
<code>python2</code>. 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 <code>#!/usr/bin/python2</code>,
the package needs a dependency on <code>python2</code>. If a script uses
<code>#!/usr/bin/python2.7</code>, the package needs a dependency on
<code>python2.7</code>. A dependency on <code>python (>= 2.7)</code> is not
correct, since later versions of Python2 may not provide the
<code>/usr/bin/python2.7</code> binary.
.
If you are using debhelper, adding <code>${python2:Depends}</code> 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.
