Installer won't start
Make sure you booted from the USB in UEFI or BIOS mode (depending on your system). Try creating the bootable USB again.
Installation fails partway through
Check your internet connection. The installer needs to download packages from Nixpkgs. Try again or check the GitHub issues page.
System won't boot after installation
Boot from the Abora USB again and check the installation logs or try rolling back to a previous generation if one exists.
Installation complete! Next, check out the Desktop Environments guide or jump into ANIX commands.
