What is the role of this package? It seems to handle apt operations, but why it is called repo?
We call the place where apt gets packages from a repository.
repo is short for repository.

From the _base.py file in that directory:
"""Base implementation for a platform specific repo handler.
Generally any new repo handling system would inherit from this and
implement:
- get
- unpack
- get_package_libraries
- get_packages_for_source_type
- refresh_build_packages
- install_build_packages
- is_package_installed
At the end of the `unpack` method `normalize` needs to be called to
adapt the artifacts downloaded to be generic enough for building a snap."""
and then there’s an Ubuntu repo handler that knows how to get build dependencies from Ubuntu repositories. As I understand it if and when snapcraft grows to be able to use build dependencies on, for example, Suse, this would be where you’d find a Suse repo handler that knew the details.
