After upgrdaing VirtualBox I was unable to start Docker Toolbox. start.sh script failed on step “Checking for status…” After unistalling both virtualbox and docker toolbox a number of times I have eventually found a way around the problem by alterintg start.sh. I have changed line
VM_STATUS="( set +e ; "{DOCKER_MACHINE}" status “${VM}” )"
removing the set +e to
VM_STATUS="( "{DOCKER_MACHINE}" status “${VM}” )"
Everthing still appears to work but can anyone explain what impact if any removing set +e will have please?
