Unfortunately this indicates your g++ version is too old. It looks like GalliumOS isn't being actively developed anymore so I'm not sure how hard it would be to get an update, but you need a version that supports C++17.
For Ubuntu 18.04 it looks like the last version of GCC on it was 7 and I believe 9 is the requirement for C++17 support, so your options are probably either building GCC yourself (not exactly easy) or finding a new distro that's still actively supported.
