all the commands are copy paste so you don’t need to download anything
https://github.com/sdetweil/MagicMirror_scripts

it will remove and and add the right version of node the right way, including on buster

please advise your results…

but node 20 is a mess

node 18 on buster doesn’t install

apt get update

sets up to install node 20.5.1…

Cannot find module ‘html-to-text’

ok… in the mm folder do

npm install html-to-text

then try again

but it sounds like the npm install of the upgrade failed…
which would have happened if the node 20 install failed

so you have to fix the node 20 install (with the other script)

and THEN

cd ~/MagicMirror
rm -rf node_modules
npm run install-mm

pm2 stop all
cd ~/MagicMirror
npm start

magicmirror@2.25.0 start

pm2 stop all
cd ~/MagicMirror
npm start 

does it still fail?

pm2 logs --lines=50

the logs is short above the error

lsb_release -a

Distributor ID: Raspbian
Description: Raspbian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye

I ran the script, the error remains.

see the script at the top of the scripts page and see if that helps…
https://github.com/sdetweil/MagicMirror_scripts

we know that rpi buster has a problem… not yet solved … I am working on it…

lsb_release -a

will tell you what OS release u are on
