@haggan-era, could you open a new bug on this issue? Please provide the following information:
1. version of Windows, vagrant, virtualbox, and Ruby in use on the Windows computer 2. the Vagrantfile used to create the new .box 3. any steps to reproduce the issue. On first smell it seems like a Ruby on Windows issue handling File::NULL. that was added Ruby 1.9.3 I think. I'd surmise that if you took the Vagrantfile, and ran the operation there, it'd work fine. Give that a try. If it is translating the object to a specific path reference, then that means File::NULL is platform dependent on creation of the box. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874453 Title: ubuntu/focal64 very slow to boot and reboots once To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1874453/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
