Debian is a Linux distribution that’s composed entirely of free and open-source software. It uses the apt package manager, and is the basis for the commercial Ubuntu distribution.
Since Debian 8.0, the arm64 port has been included in Debian to support this new instruction set on processors such as the Applied Micro X-Gene, AMD Seattle and Cavium ThunderX.
Debian 9 (“stretch”) supports the arm64 architecture. The Debian 9 release notes provide detail about the release, including changes from Debian 8. In addition, a full set of official Docker images for Debian can be used for your application development, including arm64 releases.
The latest stable release of Debian is 9.5. The last update to this release was made on July 14th, 2018.
