Introduction
Right of the bat, there is no official install method for Fedora Workstation as there is for Ubuntu or Debian. But it’s possible, and it is not difficult to do. In this guide I will show you how to install GrapheneOS in Fedora Linux environment. Official guide can be found here.
Prerequesites
- Carrier lock free Google Pixel device.
- Up-to-date Fedora Workstation installation
Enabling OEM unlocking
Before continuing, you need to connect your device to internet at least once. This is needed for stock OS to check whether the device was sold as locked by a carrier. In settings, go over to About phone and press Build Number repeatedly, until you see message “You’re now a developer” pop up. Then in settings, go to System > Developer Options, and below find the OEM unlocking option and toggle it.
Installing fastboot
In the official Fedora 42 repository, required version of android-tools is now available! All you need to do is just get it is just:
sudo dnf install android-tools
Then check the version. Must be at least 35.0.1
Booting into the bootloader interface
Next, reboot the device and begin holding both power and volume down buttons at the same time. Wait until you enter the bootloader interface. After that, run this to see if Fedora detects your Pixel device:
sudo fastboot devices
Unlocking the bootloader
Unlock it to enable installing custom OS and firmware. Beware that by doing so all data on the device will be wiped.
sudo fastboot flashing unlock
Getting openssh
OpenSSH is used to verify the download of OS beyond the security offered by HTTPS.
sudo dnf install openssh-clients
Downloading OS images
Follow the instructions:
curl -O https://releases.grapheneos.org/allowed_signers
To download the factory image for your specific pixel, visit releases page and find your device model codename. For example, to download the VERSION release for a device with the codename DEVICE_NAME:
curl -O https://releases.grapheneos.org/DEVICE_NAME-install-VERSION.zip
curl -O https://releases.grapheneos.org/DEVICE_NAME-install-VERSION.zip.sig
Just replace it with what you need. Next, verify downloaded images:
ssh-keygen -Y verify -f allowed_signers -I contact@grapheneos.org -n "factory images" -s DEVICE_NAME-install-VERSION.zip.sig < DEVICE_NAME-install-VERSION.zip
Don’t forget to replace DEVICE_NAME and VERSION with yours.
Flashing OS image
To extract factory images:
bsdtar xvf DEVICE_NAME-install-VERSION.zip
And run the installation script that you have extracted together with factory image.
cd DEVICE_NAME-install-VERSION
chmod +x flash-all.sh
sudo ./flash-all.sh
Locking the bootloader
After the flashing’s complete, lock the bootloader by running:
fastboot flashing lock
Now you have successfully installed GrapheneOS in Fedora 👍
