The error message you quoted is given when your head is detached
and you tried the regular "checkout an existing branch" -- which
will lose where your detached HEAD currently is.  You either say
"it's OK to lose it because I am done with it and I do not need
to keep it anymore" with "-f", or you say "I am done with this
detached state for now, but I know I need to revisit it later"
with "-b".

So if you will not use -b with it to discard a temporary state
that is detached HEAD, that is perfectly fine.  Detached head is
useful.
