@sdetweil i think i will just lean on the browser feature - npm run server seems to work. thanks for all your help!

[sdetweil]

@the_2winz what platform is this?

Google search to find the system command to install that library

[the_2winz]

@sdetweil Debian Bullseye with Raspberry Pi Desktop

[sdetweil]

@the_2winz weird. haven’t seen that error in a long time on that

did you install MagicMirror w my script or manually?

[the_2winz]

@sdetweil both actually. I ran npm run install-mm, then i ran your upgrade-script.sh got this Check current Node installation …

@the_2winz did u find the command to install libnss?

[the_2winz]

@sdetweil I found this Install libnss3 deb package: sudo apt-get install libnss3, but get this: /usr/lib/x86_64-linux-gnu $ sudo apt-get install libnss3

@the_2winz and now MM should start ok
you should not be running MM as root user…

[the_2winz]

@sdetweil still get this
rob@raspberry:~/MagicMirror $ npm run start

magicmirror@2.25.0 start
DISPLAY=“${DISPLAY:=:0}” ./node_modules/.bin/electron js/electron.js

@the_2winz

sudo apt get install libnss

edit:

on my desktop I see

libnss3.so => /usr/lib/x86_64-linux-gnu/libnss3.so (0x00007f2630707000)

from

ldd ~/MagicMirror/node_modules/electron/dist/electron | grep libnss
