ryFile could not be unwrapped Error when upgrading X440G2

[B_]

I am trying to upgrade an X440G2 switch from 30.7.2.1 to 31.7.1.4 and am getting this error:

Error: Failed to download image - Error: File could not be unwrapped.

Searching hasn't revealed anything useful, what does this error mean specifically?

Hi,

That points to a possible checksum mismatch:
