Hello,

You can upgrade your existing installation of Fedora 32 with the following steps.

First, if you are in Windows 1903 or newer first backup your installation:

wsl --export fedoraremix fedoraremix32_backup.tar.gz

Then proceed:

upgrade.sh
sudo dnf upgrade --refresh
sudo dnf install dnf-plugin-system-upgrade
sudo rpm --import https://src.fedoraproject.org/rpms/fedora-repos/blob/rawhide/f/RPM-GPG-KEY-fedora-33-primary
sudo dnf install distribution-gpg-keys
sudo dnf system-upgrade --allowerasing --skip-broken download --releasever=33
sudo dnf system-upgrade reboot

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

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

exit

If you face an error like: "Failed to obtain the transaction lock (logged in as root).". Run this:

upgrade.sh

And repeat the last command that you attempted and keep following the steps.
