arm build broken on master due to rust 1.39.0 no longer available
Getting this error building tip of master branch today on raspberry pi:
Rust version, use your package manager or rustup:
rustup toolchain install 1.39.0
rustup default 1.39.0
The suggested rustup commands work on x86_64 but not on armhf, it appears that the 1.39 version for this architecture is gone from the rustup servers. Please upgrade required rust version or provide workaround.
