Can you just stop calling it a dirty hack ffs?

That's just your judgement on these things Ralf.

You have used the words "dirty hack" at least 10 times in these 
messages.

There is nothing wrong with using a quick solution that works.

If removing tracker removes Ubuntu-Desktop or something similar than no, 
it's not a good solution.

Asking for trouble is a lie, in all likelihood there wouldn't ever be 
any issues.

No, that's like saying that throwing away an apple and eating it are the 
same thing.

Just because the upgrade removed the older versions doesn't mean purging 
the older versions directly would have been a good idea.

Stop muddying the waters please and just give clear advice next time 
instead of saying that apples and oranges are the same now in order to 
not lose face???

Yes, terrible.

Of course bugs are not.

Yeah, just no one mentioned installing something from Yakkety when it is 
that easy and not any more risky than installing and compiling your own 
versions as packages, obviously much less so.

Stop making people scared for no reason.
