I tried to get the D ecosystem up on:
Aarch64 Debian 9 - Has GDC (no DMD) , but no DUB package.
x86 Ubuntu Bionic - Has DUB, but no DMD. Default installs LDC.
x86 Arch - Has modern everything in standard repos.
Its just odd, that a language which is fairly popular, more popular that others which are fully supported in most distros, is kinda forgotten.
