When executing the command
circleci local execute
you may get the following error if your version of Docker is using cgroups v2:
Error: Unexpected environment preparation error: error looking up cgroup: not implemented for cgroup v2 unified hierarchy
Please use cgroups v1 as we do not support cgroups v2 on our current version of circleci-cli at this time. You will need to downgrade and pin the circleci-cli tool to a previous version. More detailed instructions and discussion can be found on our CircleCI-Public / circleci-cli page.
