I get the following error in the script, when it gets to thee part about loading the graphical file chooser for the backup location

Note: Backups will first be made on the drive this script is located in, and then will be copied to the specified location.
Running on Windows (WSL) - a graphical file chooser dialog will be open.

I haven't upgraded to Windows 11 (honestly mostly because I would like to keep my taskbar on the side >_<) but it seems that most recent Windows 11 (and specifically Insider Builds) are required for the script as the directory choosing option requires a Linux GUI to choose the backup destination. Is this the case? If so, is it possible to enter the directory manually instead? I have no problem with GUIs, but for choosing an install directory, I don't think commandline is too far behind (I suppose it depends on if it's freetext vs completion). Is my understanding of the situation correct?

I wrote this feature on Windows 10 and it worked perfectly in my testing, so this shouldn't occur. Could you try installing libqt5x11extras5 on your Ubuntu container and see if it fixes the issue?

Thanks for answering. It looks like I had it installed already. Sorry, I know debugging this kind of thing is frustrating, so many different enviroments to account for, esp multi-platform. I just tried again, same result. Tried both running the .ps1 file by double-clicking in explorer, and from MS Term's Powershell.

I did find some reference to setting the DISPLAY variable export DISPLAY=:0. Before setting this when I echo $DISPLAY it shows nothing, but after setting it, it shows :0. Since I'm doing on the command line, this change doesn't persist. I could put it in one of the various config files, but I'm not sure which one, or even if its relevant at all.

EDIT: I tried adding the export line to my .profile, exited restarted terminal confirmed with echo $DISPLAY, and re-ran the ps1 script and same error.

EDIT2: I worked around this by removing the kdialog section in functions\backup_func.sh:

    # Check if we're running on Windows.
    # If we are, then we will open a file chooser instead of asking the user for the file path thru CLI
    # due to compatibility issues.
    # TODO: also do this on Linux if KDialog is available
    #if [ "$(uname -r | sed -n 's/.*\( *Microsoft *\).*/\1/ip')" ];
    #then
    #   cecho "Running on Windows (WSL) - a graphical file chooser dialog will be open."
    #   cecho "You will be prompted for the backup location. Press Enter to continue."
    #   wait_for_enter
    #   archive_path=$(kdialog --getexistingdirectory /mnt/c || true)
    #else
        text_input "Please enter the backup location. Enter '.' for the current working directory." archive_path "."
    #fi

This is very crude naturally, but it did allow the backup to progress, seems to be working, will see if it completes successfully. Also, after execution, the .sh file is reverted back to original? Not sure exactly. In any case, this seems to be easier solution than debugging the above, but getting the GUI part working would of course also be preferred.

I got an error, on the Exporting Contacts section:

Exporting contacts (as vCard).

Related in any way? If not, any ideas about this? I don't really need my contacts exported, but just don't want it to affect any other part of the backup, either the actual backing up, or down the line, any restoration.

This is a known issue. Use the adb exporting method.

I can reproduce this on Windows 11 22H2 (works just fine on Windows 10 for me though)

It seems like WSL doesn't auto-update and sometimes even ships with an outdated version that's incapable of running GUI apps. The latest commit (https://github.com/mrrfv/linux-android-backup/commit/b61945de1b68268081ab933f26ccc2f55478e1e9) fixes this by ensuring WSL is fully up-to-date before continuing.
