We tried to resolve this. But still facing the same issue.
https://imagebin.ca/v/2vp4lLEvyDQi

and While bootstrapping process going on, we ssh into that machine and under /etc/apt/apt.conf.d  we added Acquire::CompressionTypes::Order:: "gz";  to avoid hash sum mismatch issue. But curtin script is very fast and change is not reflecting. Now what i need to do?
