Updated from scratch in gist with latest Arkane systems genie repository

The same error happens for me too: Failed to fetch https://wsl-translinux.arkane-systems.net/apt/InRelease Could not resolve 'wsl-translinux.arkane-systems.net' and ./wsl2-setup-desktop-gnome.sh: line 56: syntax error: unexpected end of file.

Same:

Some index files failed to download. They have been ignored, or old ones used instead.
./wsl2-setup-desktop-gnome.sh: line 56: syntax error: unexpected end of file

Run script raised error:
The repository 'https://ppa.launchpadcontent.net/communitheme/ppa/ubuntu jammy Release' does not have a Release file.

@b23prodtm below statement is wrong, and script fails

But it fails with following, seems wsl-transdebian for Ubuntu24 not available, only Ubuntu22

E: The repository 'https://arkane-systems.github.io/wsl-transdebian/apt noble Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

W: Failed to fetch https://wsl-translinux.arkane-systems.net/apt/InRelease Could not resolve 'wsl-translinux.arkane-systems.net'

"gnome-session
Terminated"

Is this project still alive? Would very much like to have Gnome desktop environment on my Windows machine.

EDIT: I somehow got it working yesterday. I then reinstalled Ubuntu because of other reasons and now can't get it to work again. This time I'm getting

"dbus-launch --exit-with-session gnome-session
dbus[1015]: Unable to set up transient service directory: XDG_RUNTIME_DIR "$HOME/xdg" not available: No such file or directory
Terminated"
