LLVM Debian/Ubuntu nightly packages
The goal is to provide Debian and Ubuntu nightly packages ready to be installed with minimal impact on the distribution. Packages are available for amd64, i386 (Debian only), s390x and arm64 (aka aarch64). This for both the stable, qualification and development branches (currently 18, 19 and 20). Packages are built using stage2 and extremely similar to the one shipping in Debian & Ubuntu. The pack
