Upgrade Fedora Remix for WSL to 40

You can upgrade your existing installation of Fedora 39 with the following steps.

First, backup your installation:

wsl --export fedoraremix fedoraremix39_backup.tar.gz

Then proceed:

NOTE: DO NOT PERFORM THE UPGRADE STARTING FEDORA REMIX WITH SYSTEMD; IT WILL RUIN YOUR INSTALLATION

#Be sure that systemd is disabled
[ "$(grep -c "^systemd.*=.*true$" /etc/wsl.conf)" -ne 0 ] && sudo sed -i "s/^systemd.*=.*true$/systemd=false/" /etc/wsl.conf && wsl.exe --terminate ${WSL_DISTRO_NAME}

update.sh 
sudo dnf -y upgrade --refresh  
sudo dnf -y install dnf-plugin-system-upgrade  
sudo rpm --import https://src.fedoraproject.org/rpms/fedora-repos/raw/rawhide/f/RPM-GPG-KEY-fedora-40-primary  
sudo dnf -y install distribution-gpg-keys 
sudo dnf -y system-upgrade --allowerasing --skip-broken download --releasever=40  
sudo dnf -y system-upgrade reboot

At this point, it will raise an error, ignore it, and execute the following commands:

sudo dnf -y system-upgrade upgrade   
sudo dnf -y autoremove   
sudo dnf -y clean all   
sudo mandb  
sudo dnf -y system-upgrade clean
update.sh  
cat /etc/fedora-release

exit

You can then reenable or start with SystemD if you were using it.

Enjoy it!
