The PR #228 [1] changed to use jq instead of sed to parse yaml when relocating two lines. However, yaml format is not supported in versions prior to juju 3.x.
$ juju show-cloud localhost --format json
ERROR invalid value "json" for option --format: unknown format "json"
Therefore, we need to revert back to the previous two lines to support both juju 2.x and juju 3.x simultaneously.
