UNSOLVED MMM-AssistantMk2: error on authentication test

[mc_landin]

I cannot seem to get th MMM-AssistantMk2 module to work. I’m stuck at “In your SBC, you can run auth-tool for authentification. (not via SSH)”

I tried npm rebuild without success.

The error I get is

Error: /usr/lib/arm-linux-gnueabihf/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /home/pi/MagicMirror/modules/MMM-AssistantMk2/node_modules/grpc/src/node/extension_binary/node-v59-linux-arm-glibc/grpc_node.node)

First, in your previous step, was there no error?

Second,

cd ~/MagicMirror/modules/MMM-AssistantMk2
npm install --save-dev electron-rebuild
./node_modules/.bin/electron-rebuild

Doesn’t work? You’d got error?

Try these;

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

Then, try again.
