Minimize.sh script fails OSX builds

[chocolatewheelchair]

Host machine: OSX 10.10
Using the boxcutter templates, unadulterated.

Am consistently running into the following error for every OSX packer build:

==> vmware-iso: Provisioning with shell script: script/minimize.sh
    vmware-iso: ==> Turn off hibernation
    vmware-iso: ==> Get rid of the sleepimage

Build 'vmware-iso' errored: Retryable error: Error removing temporary script at /tmp/script_7943.sh: dial tcp 172.16.250.137:22: connect: host is down

==> Some builds didn't complete successfully and had errors:
--> vmware-iso: Retryable error: Error removing temporary script at /tmp/script_7943.sh: dial tcp 172.16.250.137:22: connect: host is down

Builds succeed if i comment out the minimize.sh script so the issue definitely seems to come from there, but I have no idea what´s up. Pointers anyone?

Edit: when running packer in headless_mode: "false", it seems packer tries to remove the temp script after having shutdown the machine, hence why it cannot remove the script or communicate with the vm at all

Try running with PACKER_LOG=1 packer -debug <args> to see exactly where it is going wrong.

I increased the timeout on shrink to compensate for older/slower machines. It appears to be related to the speed that your computer perform the shrink operation, and whether that is faster than the default packer retry timeout:
