EDIT: this may not be relevant if all your Pis are Pi3B+
Not all images will work on a Pi3B+. Try a new download of the latest Raspbian.
Older Raspbian Stretch images can be updated on an older Pi:
Code: Select all
sudo apt update
sudo apt full-update
Older Raspbian (Jessie, Wheezy) and other OSs are more tricky -- results not guaranteed.
You need to say what OS and its version/date and maybe someone can help.
Likewise NOOBS can be updated but a new image is easier.
