Full version Emoncms with external USB 250G Drive

Emoncms Installation

I get errors when installing php7.0 starting with “Package php7.0-common is not available”
Previously, when I used NOOBS 3.0, I was able to install this, now that I am using NOOBS 3.2 I can’t install php7.0. Either something changed with Linux version or something changed with php package?

Thanks in advance for any assistance?

I am using the “Install Emoncms on Raspberry Pi (Raspbian Stretch)”
At emoncms/readme.md at master · emoncms/emoncms · GitHub
Noobs 3.1 Raspbian Lite

I get to “Install the dependencies:”

Correct, if you use the latest NOOBS you will get the latest Raspbian version which is Buster not Stretch. Buster installs PHP7.3 not 7.0 see the Raspberry Pi 4 thread about moving to using more generic “php-” package names and letting the package manager install the correct packages.

@dlmpryor - we are reasonably close to replacing these instructions with a set of scripts for the install. Is this a fresh Raspbian Image you are building this on? If so, you would be better with Raspbian Lite as the base image.

Thanks Paul & Brian,
For now, I will roll back to NOOBS 3.0.
I won’t wait for the Raspberry Pi 4 using more generic “php-”

Yes, this is a fresh Raspbian image, so I will be sure to select the Raspbian Lite as the base image.
Thanks for the tip.
