You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

go get -t -d ./github.com/digitalocean/ceph_exporter/...
go: go.mod file not found in current directory or any parent directory; see 'go help modules'
Failed to run 'go get -t -d ./github.com/digitalocean/ceph_exporter/...' for 'ceph-exporter': Exited with code 1.
Verify that the part is using the correct parameters and try again.
Run the same command again with --debug to shell into the environment if you wish to introspect this failure.
