Hassio Addon from store will not install

My Pi literally burned up. Scorched circuits etc.
I have now installed Hassio in docker on a NUC. Also have Nabu Casa installed as well.
I am attempting to rebuild the system (doing a better job this time)

My big problem is that when I go to the hassio add on store the files will not install.

What can I look at to diagnose. I am using the same file permissions as before.
Any help greatly appreciated.
