Haxelib upgrade openfl throwing error

Don’t remember doing anything funny to the install but tried to check if everything was UTD and got this:

error: cannot lock ref ‘refs/remotes/origin/release’: ‘refs/remotes/origin/release/6.0.0’ exists; cannot create ‘refs/remotes/origin/release’
From https://github.com/openfl/openfl
! [new branch] release -> origin/release (unable to update local ref)
error: some local refs could not be updated; try running
‘git remote prune origin’ to remove any old, conflicting branches

is this a temp thing or should something be done to correct this ?

Perhaps a clean clone of the repository would help?
