I have no idea too, maybe something is misconfigured, I never did
something else than apt-get install in a terminal.

The .local files are always owned by the user, but I want to add, that
it is a link to another partition. This worked perfect with Ubuntu
16.04. IMHO it should be enough permission, so a user can read it. But
in this case, the user can write it too. With 16.04 another user could
use it too.

No this was my suggestion for APS-C, but ther is one for cropfactor 1,
which I posted earlier in this thread.

At the moment I am talking only of automatic correction.

Yes, and therefore I added a line:
<lens>
<maker>Sigma</maker>
<model>Sigma 70-300mm f/4-5.6 DG Macro</model>
<model lang="en">Sigma 70-300mm F4-5.6 DG OS</model>
<mount>Sony Alpha</mount>
<mount>Sigma SA</mount>
<mount>Pentax KAF2</mount>
<mount>Canon EF</mount>
<mount>Nikon F AF</mount>
<cropfactor>1</cropfactor>
This works, if I remove all other Sigma 70-300mm entries.
BTW I have another lens, which is not recognized, but was with
Ubuntu 16.04.
Tamron SP AF 28-75mm F2.8 XR Di LD Aspherical [IF] Macro
I can provide a sample tomorrow, if you want.
