Just for clarification:
- On Debian 10 and Ubuntu 18.04 the php-kolabformat 1.3.0 update should indeed not be available
- With the 1.3.0 update the kolabformat.php file is expected to no longer exist, as it is not required by php and no longer generated in more recent swig variants.
- Kolab is not currently php 8 compatible (though we are working towards it).
