Hi smomni,
We have been having the same problem with our virtual machine app (QEMU x86 64bit), only on VMs running 2.14.3+rev1. We have a thread here but no Resin replies yet.
My colleague managed to get a device running an image successfully just by leaving the VM to download-loop for 5 hours.
I ran mine for 7 hours (13 download/extract/fail loops) with much more memory but didn’t have any luck.
Older releases operate correctly if you need a quick workaround.
