Occitan was added to localechooser in 2.89ubuntu1 through the merge from Debian. However, that was after the old way to have ubiquity import the languagelist was broken, so it's still not in ubiquity.
The loose end in connection with bug #1943768, i.e. the two ubiquity merge proposals linked to that bug, is related. You rejected my MP to update the localechooser subtree from 2.89ubuntu3, while your own MP has not yet been merged.
So any update of the languagelist is currently blocked, so to speak. Please unblock it somehow.
@Steve: Looks like we need your help to fix this.
