[pkg] Add new autopkgtest for skeleton packaging When running `cubicweb-ctl newcube`, the generated template provides debian packaging. So let's add automated tests for that using autopkgtest. The new test will generated a new cube, build a source tarball, build the package, try to install it, see if the Python 2 and 3 modules are available and even run autopkgtest against the newly created packages. Along the way it will also print information about the generated package: buildinfo, package content, and lintian report.

from os import unlink
from os.path import isfile, join
from cubicweb.cwconfig import CubicWebConfiguration as cwcfg

regdir = cwcfg.instances_dir()

if isfile(join(regdir, 'startorder')):
    if confirm('The startorder file is not used anymore in Cubicweb 3.22. '
               'Should I delete it?',
               shell=False, pdb=False):
        unlink(join(regdir, 'startorder'))
