Tried running snapcraft while I had a virtualbox instance running, got this error: SNAPCRAFT_BUILD_ENVIRONMENT_MEMORY=8G snapcraft Launching a VM. start failed: Another virtual machine manager is currently running. Please shut it down before starting a Multipass instance. An error occurred with the instance when trying to start with 'multipass': returned exit code 2. Ensure that 'multipass' is setup correctly and try again. I guess this is a fundamental multipass issue.
