I have a Pixel 7A, decided to install GrapheneOS on it, I'm on an laptop running Linux Mint off a external hard drive (used to be my old laptop hard drive but now in a case as an external hard drive) and using Brave (shields turned off no incognito mode) as I'm using the web installer, I'm also using the cable that came with the device on the USB-C port of my laptop (turns out it had one)
Everything was going accordingly, the bootloader unlocked, the latest release downloaded but when it was time to flash I got this message.
What should I do now?
