Node crashes after latest update.

[DenaFrancis]

Hi, I am using the raspberry pi 4b to run the node after burning an image file onto an sd card. I have run into a problem after updating the node to the latest (3/12/2020 version) on the ethoscope updater( http://node:8888). After rebooting the node, it looks like the node is no longer working and cannot be accessed online.

The administration tab is blank:

I can, however, still ssh into the node and it seems to be connected to the ethoscope and the internet as I can ping these and there is a signal.

My Node also fell over after initiating an upgrade from the ethoscope web interface, and then restarting the system.

I now get the following errors in the system log:

This looks like an issue with the updater not properly building the new Python Egg. Using the terminal. please go inside the ethoscope/node_src folder and issue the following command:

sudo python setup.py develop

Yep that does seem to have fixed it.

Yes, it now shows that everything (including the ethoscope is updated). Would we need to do this after every installation? or will the newer versions fix this? Thanks a lot.

Just an update: after the node and ethoscope software was updated, the ahavi-daemon in the ethoscope was not able to run after rebooting the system. I went back to clear the journal logs again and the ethoscope reconnected after that. I can't seem to save/add any user/experiment information through the node though...and I am not sure how to fix this.
