      @sdetweil I’m sorry for the question: that script?

      bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)”

      Thanks

        @nowayto yes, but its two steps

        one time without any parameters (test mode)
        and one time with apply

        all you have to do is click/copy the first time and run it
        then do the same on the second if the first ends successfully

          @sdetweil MM doesn’t work.

          I tried a config check but I have this error now.
          I tried to “npm install eslint -g” but the error persist

          npm run config:check

          magicmirror@2.31.0 config:check
          node js/check_config.js

            @nowayto show me the ~/MagicMirror/installers/upgrade.log

            note: I had a typo in log filename

            and then do

            cd ~/MagicMirror
            npm install

                npm seems to see an old version of nodejs but:

                ~/MagicMirror $ node -v
                v22.15.0

                I don’t know what happened.
                If it can help I had first problem after the MMM-SolarPicture
                but I’ve just installed it and configured it through config.js… nothing more than usual…

                but the actual behaviour is that pm2 status says it’s running, but on the monitor I see just the raspbian desktop

                  @nowayto two things

                  doing test run = true, NO updates will be applied!
                  upgrading from version 2.31.0 to 2.31.0

                  doing test run changes nothing, its a safety check

                  and i wont let you upgrade over the same release accidentally

                  so you need to rerun the command and add

                  force
                  

                  to the end

                    @nowayto NEVER use sudo with any npm command

                    the number in the pm2 status 4311 is the number of restarts

                    youve got a mess

                    now we HAVE to use sudo to undo it

                    cd ~/MagicMirror 
                    sudo rm -rf node_modules
                    cd fonts
                    sudo rm -rf node_modules
                    cd ..\vendor
                    sudo rm-rf node_modules
                    cd ..
                    

                    lets see about node

                    which node
                    n 
                    q to quit
                    nvm 
                    

                    dont do anything else til we figure out the nodejs problem

                      @sdetweil I’m sorry :(

                      I did it what you suggest and config:check gave me a module error again. Different than one before

                      npm run config:check

                      magicmirror@2.31.0 config:check
                      node js/check_config.js

                      node:internal/modules/cjs/loader:1404
                      throw err;
                      ^

                      Error: Cannot find module ‘ajv’
                      Require stack:

                      After “require stack” there are other lines, if you need it, tell me.
                      Thanks

                        i said stop

                        we need to fix nodejs so npm install will work

                        node -v

                        says something
                        and npm install says node is different

                        i am trying to figure out where node is installed and by who
                        system, nvm or n

                        you didn’t give me answers to the commands i provided

                          which node gave me
                          /home/MYMIRR/.nvm/versions/node/v22.15.0/bin/node

                          n gave me
                          node/20.18.1

                          Use up/down arrow keys to select a version, return key to install, d to delete, q to quit

                          nvm gave me

                          Node Version Manager (v0.39.5)

                          Note: refers to any version-like string nvm understands. This includes :

                          • full or partial version numbers, starting with an optional “v” (0.10, v0.1.2 , v1)
                          • default (built-in) aliases: node, stable, unstable, iojs, system
                          • custom aliases you define with nvm alias foo

                          followed by a lot of options

                            @nowayto ok nvm and n do the same function but differently

                            i use n in my scripts because it runs everywhere

                            so lets turn off nvm

                            nvm deactivate
                            nvm unload
                            cd ~
                            rm -rf  .nvm
                            

                            now which node
                            should find /usr/local/bin/node

                            now we need n to get to node 22.14.0

                            sudo n 22.14.0
                            

                            now node -v

                            should return 22.14.0

                            if so, do

                            cd  ~/MagicMirror 
                            npm install
                            

                            now MagicMirror should run

                                @nowayto so that sounds like the npm install failed again

                                do it again and show the output

                                      I’m sure.I don’t think SolarPicture could be the problem.

                                      Yes, the error keep showing

                                        @nowayto wild, lets do this… intall MM again, but save the current…

                                        #backup MM config and modules list
                                        bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_backup.sh)"
                                        #rename the MagicMirror folder out of the way
                                        cd ~
                                        mv MagicMirror MagicMirror.save
                                        #and install MM again
                                        bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"
                                        #restore the  MM config and modules
                                        bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_restore.sh)" 
                                        

                                        then

                                        cd ~/MagicMirror
                                        npm start

                                          Before writing here I made backups, locally and on github, like you taught me in the past :)

                                          Now I’ll try

                                            That’s incredible… I did it, everything goes good… no issues but when I start it

                                            npm start

                                            magicmirror@2.31.0 start
                                            npm run start:x11

                                            magicmirror@2.31.0 start:x11
                                            DISPLAY=“${DISPLAY:=:0}” ./node_modules/.bin/electron js/electron.js
