Here’s the output code

sudo php test_redis.php

Can you post the output from this please?

Is this a clean & fresh Ubuntu installation or have you just upgraded?

64

Try without the sudo.

65

I’ve renitialized the system and will install the script emoncms again, maybe the error is in ubuntu and not in emoncms.

I’m sorry, I really do not know what else to suggest.

I have now run the script multiple times on a fresh install of Ubuntu 18LTS (I reset the VM each time) and it just works apart from the few additional modifications I have outlined.

This looks like there are fundamental bits that have not installed correctly.

Do you have another version of emoncms that is stable?
69

It is not the software itself that is not stable, it is the mechanism to install it on systems other than Raspbian.

@TrystanLea is currently working on the scripts so they will be unstable at the moment. We are working on getting these right rather than trying to fix the documentation right now. Not ideal, but it is what it is.

Okay, thanks!
