Please help to install graphene OS on my pixel6a, to install the OS through the device, it just rebooted in the bootloader and that's it. The bootloader unlock was able to reinstall the OS, but now I can't lock it again.
When entering a command
fastboot firmware lock

I get an answer

FAILED (remote: "invalid android images, skip lock")
fastboot: error: command failed

On the site https: //flash.android....uejay-user&signed=true also plans to install the OS and block the bootloader, but gives an error. During installation, the device reboots into the bootloader and the site gives an error that the device is busy.

At the moment, when you turn on the phone, only a white screen with the inscription google.

I have Manjaro Linux on my PC, but it's unlikely that grapheneOS developers for Arch will also get a guide for this problem.

Also the team
OEM fastboot lock
issues

FAILED (remote: "Invalid oem command lock")
fastboot: error: command failed

    alex556 we do not officially support Manjaro. You must follow ALL the directions/instructions provided if you wish to receive support.

    To outline:
    https://grapheneos.org/install/web

    Officially supported operating systems for the web install method:

    • Windows 10
    • Windows 11
    • macOS Catalina (10.15)
    • macOS Big Sur (11)
    • macOS Monterey (12)
    • Arch Linux
    • Debian 10 (buster)
    • Debian 11 (bullseye)
    • Ubuntu 20.04 LTS
    • Ubuntu 22.04 LTS
    • ChromeOS
      -GrapheneOS
    • Google Android (stock Pixel OS) and other certified Android variants

    Ensure you use the stock cable, if this doesnt work it'll be down to how the port is implemented on your device. To mitigate this ensure you have a standard compliant USB A-C cable from a known good manufacturer such as Anker, Aukey or Belkin.

    The easiest way is to use stock cable and another Android device. If you hit an error on the web installer ensure you copy it here when seeking further assistance.

      MetropleX and other certified Android variants

      Why only certified Android variants? WebUSB is supported by almost all Chromium-based browsers on Android

      Manjaro is a rolling release updated frequently. In addition the Google Chrome Brownser is updated frequently. So one person might get results but another at a different time may not.
      I got good results with Ubuntu, Xubuntu, and Fedora but I was using CLI.

      I think it best to use one of the Debian-based distrols.
