Local sh script incomplete installation

[DatDraggy]

I recently claimed my rewards on a Ubuntu 20 VM, but I noticed during ./install.sh neither metadata.bin nor the libs required for keccak or sha3sum were installed. I had to build and install maandree/libkeccak and maandree/sha3sum, then change the sha3sum line to keccak-256sum and finally got a working proof back. I'm unsure if I'm missing something but surely this can't just be me? I only tried the sh script, no other approach so maybe people usually go for something else.
