WSL2 Upgrade Debian 10 to Debian 11 "bullseye" [Easy way]

When I Installed WSL by default it installed Debian 10 which was the latest version available that time.

Not latest version of Debian bullseye released. 

Method 1: Fails

Try to execute

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
 
sudo apt update -y && sudo apt full-upgrade -y

Method 2: Working Method confirmed in 2022


Open sources.list file and change every buster to bullseye 

sudo vim /etc/apt/sources.list



to 



This above version is the modified sources.list to update the debian to bullseye Debian 11 version.


Then execute following command:

sudo apt full-upgrade
 




Everything Upgraded.


Make sure to run 

sudo apt update -y && sudo apt upgrade -y
 
Then Close and reopen the Terminal/Powershell/Bash window
Check your debian version now


Thats it.

  1. Do you think something similar to the above will work to upgrade from 11 (bullseye) to 12 (bookworm)?
