All ports disappear via webinterface after EVOK update on L203



  • I use the image UniPian-Neuron-OS-2018-06-15.img on NEURON L203 (there already is correct file /etc/apt/sources.list.d/unipi.list and ngix)

    After I did an EVOK update according to
    https://github.com/UniPiTechnology/evok

    sudo su
    apt-get install unipi-modbus-tools
    apt-get install evok
    reboot
    

    and now, I don't see any ports via webbrowser as below
    0_1539864698756_4fa558f3-56a2-42a6-9cfd-8ecbb913e17a-image.png

    How can I fix it?


  • administrators

    It looks like EVOK is not running. Please try using:

    sudo su
    systemctl status evok
    systemctl status unipitcp
    

    The output should at least say what's gone wrong. I will try to replicate it locally as well, but it may take a while.

  • hi, any updates?


  • administrators

    @wizro_pl Was it installed on a clean Raspbian? It might not work if evok was previously installed not using the package system.

    Can you also paste the output of dmesg and sytemctl status unipitcp?



  • As I mentioned above I've used prepared by UniPi image of rasbian with evok embedded called "UniPian-Neuron-OS-2018-06-15.img". Reason, why I tried to do upgrade, was that this version didn't work correctly with api commands showed on your documentation, I couldn't control relays. I found in a thread on the forum that was a BUG which was fixed after the image release date.

    (of course before reinstall evok i did apt-get update; apt-get upgrade)

    dmesg:

    @wizro_pl The thing is that the evok installed from debian package is not compatible with the one installed as mentioned on github. To make it easier, please use the Raspbian stretch lite and install evok according to the guide on Github. We will publish a UniPian OS with the package version of evok soon.
