Ruby 2.3 is unsupported

ohaiwalt commented 5 years ago

@wimo7083 and I discovered last night that the backend is running on Debian Jessie, and while attempting to upgrade to a more recent version for OS support, we found that the backend Docker base image is Ruby:2.3.3. Ruby 2.3 is now unsupported as of March 31st, 2019. From that link:

We highly recommend that you upgrade to Ruby 2.6 or 2.5 as soon as possible.

There's a variety of upgrades that need to happen here to bring us to more current (and supported) toolchain versions.

Ruby version >=2.5
Rails version to whatever supports Ruby >=2.5
Debian Jessie -> Debian Stretch or better

I opened #484 to see if tests would pass, but they did not. If anyone wants to investigate upgrading Ruby and Rails, I am happy to assist with troubleshooting in that effort.

I'm taking a stab at this now. I'll have a few PR's open shortly related to this
