Hello,

Our teachers need WSL (Windows Subsystem for Linux) for the NSI option.
The WSL package from the Wapt Store doesn't install WSL even after a machine restart (W11 Education 64-bit).

However, the installation task logs are OK:

Ensure wuauserv Auto Update option is disabled
Installing WSL
re-enabling wuauserv previous state: 0
A reboot is required to use WSL
Installed: lfkl-wsl(=1.0.1-13)

Since we're using Wapt Wua, I think this might be preventing the WSL download because the package runs (too) quickly to download WSL.
Even though setup.py does contain the command to disable it during installation (as seen in the log).

Would it be possible for you to test and possibly correct the package if there's an error?

Thank you in advance, sincerely,

Wapt console 2.6.1.17786 and Wapt server on Debian 12.14

Hello,

After some testing, I haven't been able to reproduce your problem. WSL installs correctly but immediately prompts me to update to version 2. Could you please describe the output of the `wsl` command on the affected machine? Do you receive an error message?

Alternatively, you could try installing the package directly from https://wapt.tranquil.it/store/fr/tis-wsl2 ?

Sincerely
, Gwenaël

Good morning,

Thank you for your reply.
I followed your advice on a newly instantiated machine and tried to install the WSL2 package directly.
I get the following error:

Code: Select all

Ensure wuauserv Auto Update option is disabled
Traceback (most recent call last):
  File "C:\Program Files (x86)\wapt\common.py", line 4530, in install_wapt
    exitstatus = setup.install()
  File "C:\Program Files (x86)\wapt\private\tmp\waptj0nksv4l\setup.py", line 23, in install
  File "C:\Program Files (x86)\wapt\setuphelpers_windows.py", line 2811, in __enter__
    raise Exception('Unable to start wuauserv')
Exception: Unable to start wuauserv

Exception: Unable to start wuauserv]

When I launch WSL after restarting my machine, I get the following command prompt:

Code: Select all

Le Sous-Système Windows pour Linux n'est pas installé. vous pouvez effectuer l'installation en exécutant "wsl.exe --install".

Of course, our users do not have the rights, but if I validate as a local administrator, WSL installs correctly.

I'm a bit lost on the steps to take to fix the problem...

Thank you for your help, best regards.

Hello,

Installing WSL2 requires the Windows Update service to be running. The error you're encountering indicates that the service failed to start. Could you please verify that your service is running, perhaps start it manually with `net start wuauserv`, and then try the installation again?

Sincerely,
Gwenaël

Hello,

The "wuauserv" service was indeed disabled; however, even after re-enabling it and then attempting a forced installation of WSL2, it won't install without elevated privileges.

Since Wapt manages Windows updates on our system, I understood that it was disabling "wuauserv," and I think that's where the problem lies.
We must have an issue with our WUA configuration, but I can't seem to pinpoint it.

Regards.
