    Everything has been running well for a few months, a couple of weekends ago I noticed a message on the screen informing me that updates were available so I did a git pull in the MagicMirror folder then npm install.

    Everything seemed to have gone well, but after about 15 minutes the screen gives me a “Something went wrong displaying this web page error”. If I use VNC to login in and reload the page everything loads, and I can also load the MagicMirror from other computers on my network but it always goes back to the same error after a period of time.

    I’m using a Pi Zero if that helps with any suggestions.

      @kellogg76 is pm2 used to start mirror app?

      if so, pm2 logs --lines=100
      might show the error

      if u have modules that have a package.json file, they also needed an npm install done in their folders too…

      my upgrade script handles all that
      see here https://github.com/sdetweil/MagicMirror_scripts

        Your updater script doesn’t work on a Pi Zero.

        I’ll try running npm install in the three non default module folders.

        Thanks

          @kellogg76 >Your updater script doesn’t work on a Pi Zero.

          say what? i have tested on pi 0, 3, 4, odroid, jetson nano, and mac.
          a bunch of folks have tested on all kinds of pi’s…

          show me the log, ~/MagicMirror/installers/upgrade.log

          just for clarity the , updater doesn’t do anything by default except test the upgrade

          if u want it to DO the upgrade, u have to add the parm at the end ‘apply’

          from https://github.com/sdetweil/MagicMirror_scripts

          it should handle all the work… and give you a trial run of all that…
          
          only applying changes if u request them
          
          give it a try this works on Mac as well
          
          bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)"
          
          no changes are made to the local repo or the working copy
          
          if you WANT to actually apply the changes do
          
          bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)" apply

            ~/MagicMirror/installers/upgrade.log

            Apologies, when I ran

            curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh | bash
            

            I stopped reading after “Sorry, your Pi is not supported”, I just re-ran it and see the bit about Pi Zero’s.

              which means you didn’t add

              apply
              

              to the end to actually DO the upgrade
              like this

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

              upgrading from version 2.10.1 to 2.10.1

              correct

              u can do force instead of apply to redo the upgrade

              like this

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

                I’ll give it a try with the force option.

                Thanks

                  Unfortunately it doesn’t seem to have made any difference.

                    Ok, we/I made a change to how the mirror app starts on pi 0 or other armv6l systems.

                    But I introduced a bug. Download the fixed run-start.sh like this

                    cd ~/MagicMirror
                    curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/run-start.sh > run-start.sh
                    

                    Then start the mirror app again

                      Still the same error after doing the above and then rebooting.
