Can't install on Mikrotik ac3

[Barabba11]

Hi mates, I've troubles installing this container on Mikrotik ac3, I've used the same procedure I did succesfully on CHR (same RouterOS version 7,16), the package extracts but then keeps extracing and doing nothing, no bytes are written more to USB. I've tries also version 3.1.12 as a friend suggested me since it supports v6 processors, but same result. What can be wrong here? Unfortunately these is no helpful log. The main difference between installations is that on CHR I've used disk1, and here usb1, maybe this docker doesn't support installation on an external drive? A ful discussion with all attempts done can be see here, this friend tols he was able to run it on Mikrotik ac2, that maybe has a v7 processor. thank you for you kind support!
