 @Scott-M very interesting… only thing I can see different is the sandbox permissions I don’t have time til later today to examine any more… thanks for the feedback 
- 
 @sdetweil OK, I will keep the various SD cards with working and non working version for a while just in case it would be of help. 
- 
 @Scott-M thanks… appreciate that 
- 
 I had one more attempt at this, this time I ran an update and upgrade before running your script and this time it worked. Cannot see why that would be… Happy to experiment more if you need more info but I am going to start on building the 2 way mirror now! 
- 
 @Scott-M and my script does that before too, its in the install.log file 
- 
 @sdetweil 
 I am sorry if this has been a wild goose chase and a waste of your time. I flashed the SD card, ran the script several times and it didn’t work, I will try one more time tomorrow and leave it at that.Random results from repeating the same process are very frustrating. 
- 
 @Scott-M frustrating indeed but its normal

 Results from todays adventures writing Pi images to SD cards… I don’t really know what, if any difference there could be but I flashed 4 SD cards with the same 
 64 bit Bookworm image.2 of them, I just ran the install script and let it update the system. The other 2, I updated / upgraded first. 1 with apt full-upgrade and the other with apt upgrade and then ran the install script. The first 2 stopped at the same point on the starting server message and the other 2 just worked. When the system stops at the starting server message, CTRL-C doesn’t do anything so SIGINT is not being picked up. It may well just be something peculiar to my setup or enviroment.

 @Scott-M great feedback… I have family stuff most of the day today… did you do npm install or npm run install-mm npm run install-mm is more like what I do in the script… which limits what things npm does… npm install does everything possible 
- 
 I didn’t do either, I just ran your script from first run on the OS on the first 2 cards. On the other 2 cards, on first run of the OS I entered sudo apt update sudo apt full-upgrade bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"The only difference between them is your script not updating the system. It may all just be a coincidence and someone else with same hardware verifying would be helpful.
