$ git checkout pkg/ubuntu/zesty-devel
Note: checking out 'pkg/ubuntu/zesty-devel'.

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>

HEAD is now at c9fdde7... Update ubuntu/zesty-devel from 5.6.21-25.8-0ubuntu5 to 5.6.34-26.19-0ubuntu1

WARNING: empty directories exist but are not tracked by git:

plugin/tokudb-backup-plugin/Percona-TokuBackup
storage/rocksdb/rocksdb
storage/tokudb/PerconaFT

These will silently disappear on commit, causing extraneous
unintended changes. See: LP: #1687057.
