tracker 2.1.4+ library needs ontology files from tracker binary package

[Jeremy Bícha]

See the Debian bug for more details.

The tracker 2.1.4 libraries will exit with an error, basically crashing the app if they can't find /usr/share/tracker/domain-ontologies/default.rule which is currently provided by the tracker binary package.

The most obvious consequence is this means that nautilus won't run if tracker is not installed. But the tracker binary package isn't yet in main. The MIR is LP: #1770877

Let me give an update on the situation. For more details, see the Debian bug and its duplicate.

Tim split tracker-common out of tracker and pushed that change to the Debian packaging. This fixed this issue, but a key Debian maintainer for this package believed that this issue should be worked out upstream instead. I opened an upstream bug, but there hasn't been any patch proposed yet.

nautilus may end up needing a hard dependency on tracker because the idea suggested upstream which may work for brasero may not work for nautilus. Ubuntu can't add that dependency yet because the tracker-miners MIR isn't finished yet.

Finally, the new tracker version hasn't gotten a lot of testing in Ubuntu yet and it's not necessary for anything else in Ubuntu. Therefore, we made the decision to remove tracker and tracker-miner from cosmic-proposed today. Hopefully, everything will be in place for Daring Dragon.

We just ran out of time to coordinate everything to fix this issue.
