I am running 6.1.9 and had a similar a issue with installing an OwnCloud container after trying failing to upgrade my cache drives. Wound up having to rebuild the whole cache pool :'(. There were 5 other containers that reinstalled perfectly, unfortunately for me OwnCloud was the most important one to me.
Every time I installed the docker image it would go straight to being an orphan image, and no combination of deleting the image through the gui, deleting the image through the shell, rebooting, and standing on one foot while deleting the image did the trick.
Updated Dynamix, and the image installed successfully!
Out of curiosity, was this an issue specifically with the old version of Dynamix and 6.1.9?
