The latest update has broken deepin desktop, so I updated all deepin related packages after.
No luck anyway.

The desktop is no longer compatible with Stretch, can be installed on Debian testing or Sid.

All changes, tests and fight takes too much time so I decided to remove an installation option of deepin desktop from MinimalGUI/CLI iso images.
I also removed (temporary ?) the desktop installation and remove options from APTus.

Anyway, all packages are updated now and still can be installed via APT or Synaptic, if you would like to give it a try.

Hope I will find more time in the future to play with that again.
