deployfail due to Ubuntu bionic (18.04) moving to apt-archive.postgresql.org about dokku HOT 1 CLOSED

For better or worse, this isn't going to be fixed:

• Ubuntu 18.04 isn't supported by Ubuntu, Herokuish, or Dokku
• The failure is happening inside of dokku-apt, because its attempting to refresh your apt repos (and they don't exist for hopefully obvious reasons)
• Your version of Dokku is fairly old, having been released in October 2019

The fix is probably to at least switch to a newer herokuish. I don't know if that will work with the older version of Dokku, but it probably will? Alternative would be to customize your own version of Herokuish to use a fixed apt sources file (FROM gliderlabs/herokuish... COPY ...). You'd need to push that image somewhere, but that would be relatively easy to do with docker hub. I don't recall how to set the stack in 0.18.5, but our docs should have that (docs are versioned in this repo and also on the docs site).

If it doesn't, you need to upgrade a few things there, as nothing is supported. Thats my strong suggestion, but might not be feasible for you to do now, depending on what else you're working on. Feel free to drop by our slack/discord if you want some help with the upgrade.
