Upgrade Debian 9, (current WSL) to Debian 12 (bookworm testing)

Upgrade Debian 9 (current WSL) to Debian 12 (bookworm testing)

As of writing, the Debian distro for WSL (Windows Subsystem for Linux) is quite old.

You can get more up-to-date package managers, text-editors and compilers by upgrading WSL to Debian 12 (current testing).

  • Root required
  • Use at your own risk, preferably on a fresh installation.
  • Choose 'yes' when Debian requests to restart services.
  1. Install and open Debian on WSL (if not already)
wsl --install -d debian
wsl -d debian
  1. Go into root
sudo -s
  1. Upgrade Debian 9 to 10
apt update -y && \
apt upgrade -y && \
echo "deb http://deb.debian.org/debian/ buster main
deb http://deb.debian.org/debian/ buster-updates main
deb http://security.debian.org/debian-security buster/updates main" > /etc/apt/sources.list && \
apt update -y && \
apt upgrade -y && \
apt dist-upgrade -y
  1. Upgrade Debian 10 to 11
echo "deb http://deb.debian.org/debian/ bullseye main
deb http://deb.debian.org/debian/ bullseye-updates main" > /etc/apt/sources.list && \
apt update -y && \
apt upgrade -y && \
apt dist-upgrade -y
  1. Debian 11 to 12
echo "deb http://deb.debian.org/debian/ bookworm main
deb http://deb.debian.org/debian/ bookworm-updates main" > /etc/apt/sources.list && \
apt update -y && \
apt upgrade -y && \
apt dist-upgrade -y && \
