`yadm.os` does not resolve as "WSL" but as "Linux" in WSL2 on Windows 11

[edouardberthe]

Hello, First thank you for this amazing lib which I've been using for years now.

Describe the bug

The template functionnality seems not to work on Windows Subsystem for Linux 2 (WSL2), on Windows 11.

.config/yadm/alt/.zshrc##template:

{% if yadm.os == "WSL" %}
# Hello I am on WSL2
{% endif %}

{% if yadm.os == "Linux" %}
# Hello I am on Linux
{% endif %}

The file which is generated by yadm is: .zshrc

# Hello I am on Linux

To reproduce

Can this be reproduced with the yadm/testbed docker image: [No]

Expected behavior

As stated in the documentation, the yadm.os variable is expected to resolve as "WSL" when used from inside WSL:

Environment

• Operating system:

  • Windows 11
  • WSL: output of wsl.exe --status:

    
    Default Distribution: Ubuntu
    Default Version: 2

  Windows Subsystem for Linux was last updated on 05/07/2022 WSL automatic updates are on.

  Kernel version: 5.10.102.1

  
  - Version yadm: `2.3.0`
  - Version Git: `2.25.1`

Many thanks

What is the output of

cat /proc/version

?

yadm checks for the string 'Microsoft' in the output here.

The output of

uname -a

may prove helpful as well. Perhaps we move to that, if it's more reliable.

Can you let me know the contents of /proc/version? This is how yadm figures this out.

[edouardberthe]

Thanks for your answers.

From inside WSL2, the output of cat /proc/version is:

Linux version 5.10.102.1-microsoft-standard-WSL2 (oe-user@oe-host) (x86_64-msft-linux-gcc (GCC) 9.3.0, GNU ld (GNU Binutils) 2.34.0.20200220) #1 SMP Wed Mar 2 00:30:59 UTC 2022

and the output of uname -a is:

Linux Edouard-PC 5.10.102.1-microsoft-standard-WSL2 #1 SMP Wed Mar 2 00:30:59 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

So it's very weird, the string microsoft does seem to be present in the output..

Ok I got it, my version of yadm is 2.3.0, in which we only check for "Microsoft" (with a capital M), so I simply need to install a more recent version!

[edouardberthe]

apt update && apt upgrade yadm does not seem to install anything more recent than 2.3.0 though.

Once Ubuntu makes a release, the versions of all the packages are frozen (except for very serious bug fixes). To get a newer version you have to move to a newer Ubuntu release, which in your case is even one more step removed because it will have to propagate to WSL as well.

This is the unfortunate trade-off of distribution-packaged software: it's a lot more convenient to install and there is some effort into keeping it stable so you're not surprised by changes, but the price is that it's often out-of-date. If you need a newer version, you may need to download and install it yourself rather than using the packaged version.

Upgrade to Jammy Jellyfish ongoing :) many thanks

Upgraded my Ubuntu version (inside WSL2), which led to an upgrade of yadm to 3.1.1, everything works like a charm. Thanks!
