I wanted to audit my installed packages. I created a Python helper invoking
dpkg-query, to create a packages database using Python dictionary and lists. The helper is smart enough to check dependencies are indeed present in the dictionary cloning the installed packages database. I get an error with the
wings3d package: the helper notified me a package named
erlang-abi-13.a is missing. Synaptic tells me this package is not installed. It still list this package as a
wings3d dependency, but displays it in dependency, using italic instead of regular font.
What does it mean when Synaptic displays a dependency using italic? How a dependency may be missing while the package seems not to be broken?
