lfsx-0.24.0 is not a library.
lfsx
Command line companion for a self-hosted LFSX Git LFS server.
doctor checks that the server is up, that its storage is writable, that your token is accepted,
and — the one that matters — that the URL it advertises for transfers is the URL you reached it
on. A mismatch there lets negotiation succeed while every transfer fails.
gc reads the objects the repository still references and asks the server to sweep the rest. It
refuses to run from a shallow clone, which would retain a fraction of what it should.
The server itself is lfsx-server.
