Hi.
Did you install it on a Rasberry Pi 4, or Raspberry Pi 5 ?
I manage to install Docker on a fresh new Raspberry Pi OS 64bit, on my Raspberry Pi4, using the convenience script.
But when I do it on my Raspberry Pi5 (still fresh new image deployed, on the same 1TB SSD), after some time & steps passed I get an error, “filesystem is read-only”.
Everything’s locked, impossible to pass a single SSH command.
It happens more or less during the big apt-get install commands. I flashed again a fresh image, and retried, many times…still getting the same issue.
After googling it, I bought an official Raspberry Pi5 power supply : still getting exactly the same error.
If you have any idea which can help me a bit, you’re highly welcome 
!
