11 11  ** You can't install a 64 bit Ubuntu onto a Raspberry PI Zero or Zero W, because it requires ARMv7 processor and the Zero series is based on ARMv6.
12 12  *** Probably the smallest choice would be Raspberry Pi Model 3 A+.

14 -When installing "nodejs", make sure you're using a more recent version such as 16.x.x.  Run "node -v" to verify your node version.  If you're running an older version of Linux, you may have to manually override the installed version in order to get the version you need.  [[Here's a web page telling you how to do that.>>https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-16-04]] Following the instructions in the section "Option 2 — Installing Node.js with Apt Using a NodeSource PPA" worked for me and gave me version 16.17.0.
14 +When installing "nodejs", make sure you're using a more recent version such as 16.x.x.  Run "node -v" to verify your node version.  If you're running an older version of Linux, you may have to manually override the installed version in order to get the version you need; currently nodejs 14, 12, or 10.  I ran this command to setup apt-get to install version 14:

21 +You also need to make sure you have Mongo version 3.x or later.  You can setup the apt-get install for version 4.x here:

25 +(If you end up with the wrong version, use "dpkg -l" to see the package name.  There were probably other packages also installed at the same time, so remove all all "mongo" pages using "apt-get remove", then check "dpkg -l" to see if any are in the "rc" state.  If so, purge them with "dpkg ~-~-purge".  Finally, you can reinstall the correct version again.)

16 16  I finally ended up using a Raspberry Pi model 3 A+.  This is an ARMv7 processor, so it can do 64 bit Linux, it has built-in Wifi, and it's still small and cheap.  The system doesn't have a lot of memory, so I purchased a 32Gb micro-SD card and [[created a 16Gb swapfile>>https://linuxize.com/post/how-to-add-swap-space-on-ubuntu-18-04/]].  I installed Ubuntu 19 from here:
