Hi, I have installed Emoncms using the scripts on Ubuntu.
The backup export function doesn’t work when I press the button. The log window also don’t display any information.
Any advice?
I hit this problem before. I think it might be permissions.
Did you add a user, then install as that user?
The installation script did ask for a Pi user and then it stopped, I went back and added my user in the config file then rerun the script
Ah, but did you install when logged in as that user?
Is the service service-runner running?
I had to install the service-runner manually, its running now.
That isn’t good news. Why and how?
I followed these steps to get it working.
That isn’t good as those are old instructions and the emonscripts do things differently.
I think your issue is the same as here that I’m not sure has been fixed. All you needed to do was edit the drop-in.
My suggestion is to start again, trying to fix what you have done will probably take longer, update will not like it etc.
Happy to help as we need to fix the scripts.
Thanks, its very possibly the issue, I will restart my installation. Can you please direct me to the file location to edit the drop-in when I reinstall?
Yes. I suggest you have a read through that issue on GitHub. I think we decided that there were also issues around permissions of the Modules folder.
TBH, the simplest way is to create a user ‘pi’ and use that!
Done a fresh Ubuntu server installation, only created “pi” username.
Updated the config.ini file to change the non-pi environment.
Ran the install ./main.sh script, but the service-running did not start
I noticed that the /usr/bin/python directory does not exist.
pi@emoncms:/opt/openenergymonitor/EmonScripts/install$ journalctl -f -u service-runner

For future reference, when posting code or bash output, put in 3 ‘backticks’ (found at the top left of the keyboard normally) on a line on their own, then the code, then 3 more backticks on a line following the code.
```
code
```
If it is something like php you can add a language identifier that after the first 3 backticks so ```php
What is the result of
which python
I got no results from the command, but it would seem like Python 3.8.2 is installed but it does not have a reference to “python” and had to use “python3”
pi@emoncms:/$ which python
pi@emoncms:/$
pi@emoncms:/$ python
Command 'python' not found, did you mean:
command 'python3' from deb python3
command 'python' from deb python-is-python3
pi@emoncms:/$ python3

service-runner needs Python as opposed to Python3 (still - I’ve raised an issue). I think this must either be installed by default on the Pi, or it just so happened that service runner was picking it up on the back of it being installed for another purpose (when other modules used python).
What also might have happened is Ubuntu have changed the install as python2.x is EOL.
To check what is installed can you please run
apt list --installed pytho*
See output
pi@emoncms:~$ apt list --installed pytho*

Yes so only python3.
Try
sudo apt-get install -y python-pip python-dev

Looks like Ubuntu have dropped python from the repos.
[edit]
what does simply running python give you before you do below?
Quick Google;
Try
sudo apt install python2
Check where is is with which python
python2 installed, but see output.
No output from which python also no reference to python
pi@emoncms:~$ which python
pi@emoncms:~$ python
Command 'python' not found, did you mean:
command 'python3' from deb python3

What does which python2 give you?
What Ubuntu version are you running (bit late to ask, but hey ho)?
