Xperia 10 ii - upgrade to 4.3.0.15 fails

I am trying to upgrade my Xperia 10 ii to 4.3.0.15 but it tells me that a bunch of packages (system ones it seems!) might cause issues.
To name a few:

alienaudioservice
aliendalvik
feature-jolla
jolla-developer-mode
jolla-settings-sailfish
ssu

etc

it’s like 30 or so packages.
If I do try to install the update it fails on reboot and I’m back to square one.

On the Jolla C is complaining about (but then it installed it)
