          @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.

                @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.

                            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
