Connection to "[OS name.iso]" failed

I created a Gnome Box for a Kubuntu 64-bit image as a test run on my computer, and I cannot get it working, even after it said I successfully created the box for it.
Here are the troubleshooting logs:

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Encountered in Trusty as well. I'm not able to trace the log for this though.

[malco_2001 (jpm820)]

I was having the same problem. Further research showed the problem only occurs when "home folder encryption" is turned on.
