When trying to push a captured image from WDM 5.7, the imaging process halts during the download of the image files. After some time, the image deployment will fail with an error "sh: no job control in this shell" and it drops to the shell. The scheduled package entry in WDM 5.7 does not change to an error state and so I cannot get any error details.
I tried deploying the image with an HAgent of 18.104.22.168, WDA 2.0 and Merlin 3.3.8 with no success. Deploying the same image from USB Imaging Tool 22.214.171.124 works without an issue.
What model device are you trying to image?
