The Raspberry Pi based Curtain Controller project for my blind uncle is complete and almost ready to go to its new home. I have two RPi's - the one that is boxed up with the relay controller and one that is setup as a test environment so I can deal with any future problems or extra features.
In setting up the controller unit I obviously made a mess somewhere as nothing would install from CPAN whereas this was not a problem on the development unit. The development unit also has an HTTP server which is accessible via an ngrok tunnel ready for the unit at be Alexa enabled once I get Device Discovery working. This server needs adding to the controler and requires HTTP::Server::Simple so CPAN is necessary.
The development unit used an OS image with the network credentials added. This same image has now been used for the controller unit. So everything should be identical except that one has header pins soldered in and the other one doesn't!
Once the OS had installed and an SSH connection made I have changed the password then updated with:
With the development unit, running CPAN and typing install HTTP::Server::Simple installed lots and lots of dependencies taking nearly 4 hours but eventually installed.sudo apt-get update sudo apt-get upgrade cpan install CPAN
On the unit that is to be shipped imminently, CPAN gets 'Killed' - this is the last block of what CPAN prints out:
I've tried using CPAN to install just Try::Tiny as this seems to be where things are failing. When I do this I get almost the same output with different wallclock values reported and Lockfile removed. displayed on the line before Killed and several minutes between them.Configuring E/ET/ETHER/Try-Tiny-0.30.tar.gz with Makefile.PL Checking if your kit is complete...

Searching for an answer suggests that this is the OS killing CPAN and the most probable cause is lack of memory. The development unit has a 32Gb SD card whereas the controller has 16Gb. But, there is plenty of space on the card:

Two ostensibly identical units seem to be working differently.
Can you suggest anything I can try to debug this problem?
