Hi,

I was able to create a custom image in wic format with isar and now trying 
to create a bootable iso image. I found the wic script in the isar package 
and attempted to run with the command:
wic create mkhybridiso -e isar-image-base

However I got the following error:
INFO: Building wic-tools...

    raise CalledProcessError(retcode, cmd)

Is there any suggestion on how to resolve this issue? 

Thanks!
