Solved: Docker desktop requires a newer WSL kernel version on Windows
The integration of Docker with Windows Subsystem for Linux (WSL) has revolutionized the way developers work on Windows machines. However, encountering compatibility issues can be frustrating. One such issue arises when Docker Desktop requires a newer WSL kernel version than the one currently installed on your Windows system.
WSL, is a compatibility layer that allows running Linux distributions natively on Windows. It provides developers with a Linux environment, complete with a command-line interface and the ability to run Linux tools and applications. WSL bridges the gap between Windows and Linux, enabling developers to work with Linux-based tools and workflows without needing a separate Linux machine or virtual machine.
The specific problem arises when Docker Desktop requires a newer WSL kernel version than the one currently installed on a Windows system. Docker relies on certain features and functionalities provided by the WSL kernel, and if the version is outdated, it can result in compatibility issues and prevent Docker from running properly.
This requirement for a newer WSL kernel version can be challenging for users who have not updated their Windows system or are using an older version of WSL. However, with the right steps, it is possible to overcome this problem and ensure smooth integration between Docker and WSL on Windows.
- Identify the current WSL version
Open a command prompt or PowerShell window as Adminstrator. You can do this by pressing the Windows key, typing “cmd” or “PowerShell,” and selecting the corresponding application.
wsl -l -vThe version number typically consists of major and minor version components. For example, it might be displayed as “1” or “1.0”.
Note: If the version is displayed as “1” or “1.0”, it indicates that you are using the first generation of WSL, which may not be compatible with the newer requirements of Docker Desktop.
2. Open Windows Features
Once you open Windows features, make sure “Virtual Machine Platform”, “Windows Hypervisor” and “Windows Subsystem for Linux” are checked. If not, tick them and press “Apply”
3. Open Powershell as Administrator
You must open Powershell as Administrator, as if not would trigger a permission error. In the PowerShell, run the following command to enable WSL-1
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart4. Download WSL-2 from Microsoft Documentation
Use the link below to download the package given and run the application on your computer
5. Change the WSL 2 to your Default version
Run the below command to change the default version to WSL 2
wsl --set-default-version 2Now you are good to go! Happy coding.
