    Well…I learned something. I didn’t know about crontab logs and I found this command to try:

    sudo grep CRON /var/log/syslog

    When I did that I found this line on the end of the log:

    Apr 24 10:40:01 dave-ubuntu CRON[2931]: (CRON) info (No MTA installed, discarding output)

    I guess I need to install an MTA???

      @dwburger said in MM on Ubuntu:

      (CRON) info (No MTA installed, discarding output)

      see the last answer here
      https://superuser.com/questions/445347/why-is-my-crontab-not-running

      but that doesn’t some why pm2 was not executed
      note that you saved the pm2 config as user pi, and cron will run as root

        Hmmm…installed the default MTA for Ubuntu 18 which fixed the error message in the logfile, but pm2 still didn’t restart the MM2. I’m afraid I don’t really understand your note about pi versus root cron running. I can “sudo crontab -e” if that’s a better idea. I will add, my Ubuntu is starting up with its GUI and then I’m opening a terminal window to start MM2 using “pm2 start mm.sh”.

          @dwburger ok, but you don’t have to do ANY of this… if you used my install script, it set pm2 to autostart on boot

          to fix if you DIDN’T use my install script, use my fixuppm2 script
          see
          https://github.com/sdetweil/MagicMirror_scripts

          read the readme.

          if MM crashes, pm2 auto restarts

          YOU don’t have to have any additional commands any where

            I may have given you the wrong impression…I really don’t know my way around Linux/Ubuntu. However, I was able to run your fixuppm2 script and I now see what you mean about not having to do anything else. I’m getting the behavior I want. When I reboot my machine MM2 starts right up. I’m getting ready to make another MM2 on a mini PC running Ubuntu. This time, I’m going to use your install script!

              OK…your script did a great job in getting a new MM installed onto another Ubuntu machine. There’s one odd behavior I’m noticing. When the MM2 first comes up after power-on or reboot, not all the modules get started. I have to press the key and the File -> Close. When the MM2 comes up again all is well. I’m wondering why that is??? Is it possible to place a delay in the config.js (or somewhere else) so each module has plenty of time to get started. Maybe there’s another solution to this behavior???
              BTW…thanks for all your work on the installation scripts and the help you’ve provided!

                @dwburger i have never seen that behavior…

                do you have two entries in pm2??
                show the results of
