Answer 1

Background

In my case, I changed the location of my multipass instance locations by following this post here. I then created a folder on my drive where I wanted the instances to be stored.

After doing so, multipass launch failed with your exact same error. After trying reboots, uninstall/reinstall multipass, etc. - I finally tried renaming the folder where I wanted to store my multipass instances, and this worked.

Apparently, if your destination multipass folder includes a space, some part of the script fails.

Workaround / Fix

When specifying a multipass instance destination: MULTIPASS_STORAGE -Value "<path>"

Make sure there are NO SPACES in the "<path>" you have provided.

Hope this helps.

You have to add the HyperV module to powershell in "Turn Windows features on or off", if you don't check this the checkbox, "Resize-VHD" won't work and will fail the multipass launch.

The direct command is:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Management-PowerShell
