I just installed GrapheneOS from Fedora without any problems.
sudo dnf install android-tools
sudo ln -s /usr/share/doc/android-tools/51-android.rules /etc/udev/rules.d/
sudo udevadm control --reload
Then follow the CLI guide and download the official Google binaries as Fedora fastboot is broken.
For some reason webinstall didnt work on any device, not on my phone too (used it before!) but CLI from Fedora worked for the first time.
You need to link those udev rules as a security measurement, I will add documents soon as this is completely unexpected (and not how it works on Ubuntu afaik)
