Does this support Windows Terminal + WSL2 Ubuntu?

It seems like it tried to read the Windows env variable. So I tried adding it as a variable on Linux

$ LOCALAPPDATA="/mnt/c/Users/kela/AppData/Local/" /home/kela/.local/bin/pokemon

So it assumes you are using Windows when you're on Windows Terminal. I guess you need to read the OS type?

Correct, the script assumes Windows, and I don't think it's worth the effort supporting its use through WSL, so if WSL/Linux is detected this should be excluded from the candidate adapters (it isn't currently)

@inductor sharing how I made this work in my WSL. I changed a couple of lines directly in my installation.

First, I changed this line to:

        profiles_path = os.environ['LOCALAPPDATA'] + '/Packages/Microsoft.WindowsTerminal_8wekyb3d8bbwe/LocalState/settings.json'

Then, added this line

                wsl_path = os.environ['WSLPATH']
                profile['backgroundImage'] = wsl_path + path

I just added another environment variable: WSLPATH.

WSLPATH="C:/Users/user/AppData/Local/Packages/CanonicalGroupLimited.Ubuntu18.04onWindows_79rhkp1fndgsc/LocalState/rootfs" LOCALAPPDATA="/mnt/c/Users/user/AppData/Local" pokemon

[chardskarth]

I had to change my WSLPATH variable to \\\\wsl$\\Ubuntu-18.04 after updating to WSL2.

Hi, I know this issue was posted a long time ago, but I had exactly the same issue and was able to fix it in a very similar way with the reply given above, but slightly different.

Here I will try to explain it in a detailed way if someone has the same problem as I just did.

Instead of working with enviroment variables you can change the following in windowsterminal.py (path to this file is given explicitly by the error printed in console):

Change line number #10, which was:
profiles_path = os.environ['LOCALAPPDATA'] + '\\Packages\\Microsoft.WindowsTerminal_8wekyb3d8bbwe\\LocalState\\settings.json'
by its direct path:
profiles_path = "/mnt/c/Users/Panchito/AppData/Local/Packages/Microsoft.WindowsTerminal_8wekyb3d8bbwe/LocalState/settings.json"

in this case, "Panchito" is my Windows (not WSL) username in my configuration. You have to change that for your Windows username.

Next, in line #29 you will find the following original line:
profile['backgroundImage'] = path
and simply replace that line for the following 2 lines:
wsl_path = "\\\\wsl$\\Ubuntu-20.04"
profile['backgroundImage'] = wsl_path + path

Change "20.04" for your current WSL2 system version; in my case is Ubuntu 20.04.

If you do not know how to see you Root directory in WSL just go to root directory in WSL (type .. until you cannot go back in more directories) and then type explorer.exe .. This will open GUI Windows interface so you can easily see where your root is located in your Windows OS.

In other words, reply given by @chardskarth was really good! However, for WSL you must specify explicitly where Windows AppData (Windows Terminal json setting file) is in a way that WSL can easily understand it (which is /mnt/c/Users/...)

Cheers!
