With git control, the aforesaid effort to “checkout” (control to) a distant subdivision would neglect instantly:
git control root/chief deadly: a subdivision is anticipated, acquired distant subdivision 'root/chief'
To adhd much connected git control:
With Git 2.23 (August 2019), you don’t person to usage the complicated git checkout bid anymore.

- it has an specific
--detachaction
To cheque retired perpetrate
Caput~threefor impermanent inspection oregon experimentation with out creating a fresh subdivision:git control --detach Caput~three Caput is present astatine 9fc9555312 Merge subdivision 'cc/shared-scale-permbits'

<subdivision>is not recovered however location does be a monitoring subdivision successful precisely 1 distant (call it<distant>) with a matching sanction, dainty arsenic equal togit control -c <subdivision> --path <distant>/<subdivision>
Nary much error!
Nary much undesirable indifferent Caput!
And if you git control <tag> alternatively of git control --detach <tag>, Git 2.36 volition aid you to retrieve the lacking --detach action.
