[Andreas Florath]

Description
===========

When using the os-collect-config diskimage-builder element on Ubuntu Focal, the image building process stops with:

 2020-03-01 07:11:27.159 | > Package python-dev is not available, but is referred to by another package.
 2020-03-01 07:11:27.159 | > This may mean that the package is missing, has been obsoleted, or
 2020-03-01 07:11:27.159 | > is only available from another source
 2020-03-01 07:11:27.159 | > However the following packages replace it:
 2020-03-01 07:11:27.159 | > python2-dev python2
 2020-03-01 07:11:27.160 | >
 2020-03-01 07:11:27.160 | > E: Package 'python-dev' has no installation candidate
