having trouble fetching all remote branches

[Janek Warchoł]

My local repository wasn't created with git clone, and i have only one
remote branch ('origin/master'); i cannot push to staging because of
that.  I've tried 'git fetch --all', but the other remote branches do
not appear, and i don't see a solution in git fetch description.  Any
help?

thanks in advance,
Janek
