With rust 1.52, I run:
cargo install --git https://gitlab.com/seaofvoices/darklua.git
which results in this error output:
error: failed to find branch `master`
Caused by:
cannot locate remote-tracking branch 'origin/master'; class=Reference (4); code=NotFound (-3)
This repo never had a branch called "master", and I don't see a way to specify a differently-named HEAD branch.
