Hello, thank you very much for your quick response. I’m afraid that I am a tech beginner.
When you say make sure the bootloader is unlocked, how can I achieve that? because despite completing the installation instructions the Fastboot screen still says:
Device State: Locked (Unlockable)
Also could you please tell me exactly how I do these:

Run: flash-all.sh
At the end of the installation procedure, you can lock the bootloader again.
Basically I am having exactly the same issue as this guy. I would copy his steps but he’s using Windows and I am on Linux:
