I think you may have to configure xdg-open to do this, we don't do this by default.

az login was working for me before, but now I'm facing this issue.

[fghamsary]

I have the same issue, just installed a fresh Ubuntu 22.04 with service and GUI enabled, and the interop with browser is not working anymore on this version, there is something wired going on when using systemd with new WSL and GUI

[fghamsary]

Came accros this one: #8795
It seems like on eariler versions there was a package installed by default wslu which is not available by default on 22.04.
It had a wslview shell command which did the work, so by installing it, you can have the functionality back, but not sure of the drawbacks.

[AdamGlass]

wslu works. This really feels like a problem WSL should own -- installing the component, ensuring that the user knows the component could be installed, or forcing it to be installed due to some dependency.

it's not even mentioned here: https://learn.microsoft.com/en-us/windows/wsl/install.

(AdamGlassMS too)

Same issue here. the WSL 22.04 was working fine this morning. I did a apt-upgrade and then, the console is now broken when trying to do "az login"

I did "sudo apt install wslu" like mentioned and it seems to fix it. pretty weird what broke it

[belainehi]

I had a similar issue, considering if installing one of the "not found" packages would help. Haven't found a solution yet.

Try to add an web browser path with BROWSER environment variable before launching xdg-open. For example, let assume Firefox is installed in Windows as C:\Firefox\firefox.exe. Then set the environment variable as export BROWSER=/mnt/c/Firefox/firefox.exe and run xdg-open as usual.

wslpath can also help to covert the path style.

[AndreasNasman]

@Biswa96 Thanks for the workaround! 👍

I had to create a symlink with ln -s /mnt/c/path/to/browser.exe and then set export BROWSER=~/path/to/symlink as my browser is installed in a directory with spaces (Program Files (86)), which xdg-open can't handle.

Thanks both of you, it worked having 401 error.

Because of this change, Python's built-in module webbrowser stops working on Ubuntu 22.04 in WSL:

$ python -c "import webbrowser; print(webbrowser.open('https://login.microsoftonline.com/'))"
True

This affects MSAL's PublicClientApplication.acquire_token_interactive: https://github.com/AzureAD/microsoft-authentication-library-for-python/blob/64141cacdb4ea3a02a2b3cb45bc8fb3be4f93f36/msal/oauth2cli/authcode.py#L58

Then affects Azure CLI's az login: https://github.com/Azure/azure-cli/blob/f0c87ca820e0bd3f9dd403ef96c21ed49b734d16/src/azure-cli-core/azure/cli/core/auth/identity.py#L153

[lgmorand]

@jiasli what does that mean ? that we should consider az cli not working properly anymore on WSL 22.04 ?

[kierzorz]

@lgmorand
If you are using powershell on WSL then set the BROWSER ENV variable like so....

$Env:BROWSER = '/mnt/c/Program Files/Google/Chrome/Application/chrome.exe'

For bash on wsl to open with your default browser use:

export BROWSER 'explorer.exe'
and set this line in your bash profile to make it permanent:
nano ~/.profile

[lgmorand]

@kierzorz thanks but that's not the point. WSL is configured and install by MS, az CLI is packaged by MS. Can't we expect either a fix upstream or a built-in workaround. For instance, WSL is installed on Windows where edge is here by default (even if not default browser), so for me, the env could be setup to point to edge install path. it would be sufficient to open a web page for auth

I just installed Ubuntu 22.04. I had to do 2 things:

1. install xdg utilities (sudo apt install xdg-utils) and
2. install wslu following the instructions here: https://wslutiliti.es/wslu/install.html (Scroll down to **Ubuntu Warning**. Follow the steps for PPA version:
   sudo add-apt-repository ppa:wslutilities/wslu
sudo apt update
sudo apt install wslu

[cianetech]

@leslie-corbalt I had a lot of issues because of xdg-open not really working. Thanks to you and to the other people who mentioned about WSLU. It worked for me. I followed the steps you mentioned above.

[jiasli]

Without xdg-utils installed, webbrowser from Python 3.11 now reports a different error:

$ sudo apt remove xdg-utils
$ sudo apt install python3.11
$ python3.11 -c "import webbrowser; print(webbrowser.open('https://login.microsoftonline.com/'))"
True
gio: https://login.microsoftonline.com/: Operation not supported

[ackalker]

I'm using this on WSL2 Ubuntu with default Windows integrations (such as ability to run .exe from Linux) enabled:

$ sudo apt install xdg-utils
$ export BROWSER="cmd.exe /c start" # add to ~/.profile to make permanent
$ xdg-open https://www.microsoft.com/
'\\wsl.localhost\Ubuntu\home\<username_redacted>'
CMD.EXE was started with the above path as the current directory.
UNC paths are not supported.  Defaulting to Windows directory.

This opens https://www.microsoft.com/ in whatever happens to be my default Windows web browser.
The 'UNC paths are not spported' message seems to be harmless.
