Diagnostic Logs

Anuj-02 and me have the same issue #7565 after updating windows 10 to windows 11, but I have not found the solution yet.

I tried to previously uncheck the following functionalities in windows :

• Hyper-V
• Virtual machine Platform
• Windows hypervisor plateform

I rebooted for updated my PC.
I installed wsl functionnalities and an Ubuntu distribution via Windows PowerShell commands:

PS C:\WINDOWS\system32> wsl --install -d Ubuntu
Installing: Virtual Machine Platform
Virtual Machine Platform has been installed.
Installing: Windows Subsystem for Linux
Windows Subsystem for Linux has been installed.
Downloading: WSL Kernel
Installing: WSL Kernel
WSL Kernel has been installed.
Downloading: GUI App Support
Installing: GUI App Support

Downloading: Ubuntu
The requested operation is successful. Changes will not be effective until the system is rebooted.
PS C:\WINDOWS\system32>

After rebooting, the installation of Ubuntu continued automatically:

I also tried to update and restart the wsl service via command line :

wsl --update
wsl --shutdown

(Kernel version: 5.10.60.1)

I also tried to restart the service LxssManager via the command:

Restart-Service -Name "LxssManager"

I have no wsl.conf file in my Ubuntu distribution (/etc/wsl.conf)
My .wslconfig file contains the following lines:

[wsl2]
kernel=C:\\Users\\Anthony\\bzImage
swap=0
localhostForwarding=true

When I try to mount the C drive directly in shell, i have the same issue

anthony@DESKTOP-3QEBOGJ:~$ sudo mount -t drvfs C: /mnt/c
[sudo] password for anthony:
<3>init: (32) ERROR: MountPlan9WithRetry:285: mount drvfs on /mnt/c (cache=mmap,rw,msize=262144,trans=virtio,aname=drvfs;path=C:;symlinkroot=/mnt/) failed: 22
mount: Invalid argument

All manipulations I tried did not solve my problem. As my drive was initially crypted with Bitlocker service, il tried to put the encryption off. This did not change the issue.

Anybody have an idea to solve this problem ?
Thank you by advance.

Problem fixed : The kernel path in the .wslconfig file was wrong.

The path to the WSL kernel is located within C:\WINDOWS\System32\lxss\tools\kernel
