I just tried to update and there is a failure near the end:

I see the same error message was flagged here: ["Zlib::BufError: buffer error" - Discourse update fails](https://meta.discourse.org/t/zlib-buffer-error-discourse-update-fails/311347)
But I already have the maxmind account ID in the yaml file.
I guess I could enter the container and re-run this command again, but I wonder in general is there a way to recover from failed rebuilds or do people just try to run the whole thing again?

Yesterday i gave up and commented out maxmind. I then went into the container and added the values to discourse.conf and it pulled the database successfully (a rather complicated work around).
I don’t understand how this could be happening, but it does look like a bug.
I think the only solution now is to do without maxmind.

So I had this issue today however, It was only once, I just issued rebuild again and it went well. so weird there is no consistent way to reproduce this. other containers with similar configuration built just fine.

I’ve rebuilt 3 sites today, and each one tripped up as above at the same time, which seemed to be just after updating the Theme Components.
Each time a 2nd rebuild ran just fine, with me changing nothing at all. I do wonder if Maxmind is a bit of a red herring (or simply a different issue).
I use a 2 container setup so a failed rebuild is no big deal.

I had the same experience. It seems to fail on the first run. Luckily I switched to a 2 container set-up so the site remains live while I run the rebuild twice.

Hate to presume to report a bug but, if it looks like a duck and acts like a duck… 😉
Confirming issue with rebuilding with maxmind.
Several forums all with identical plugins all of which are Official.
From command line: Rebuilding with maxmind fails, uncomment maxmind and rebuilding works fine.
From /admin Update Discourse: no changes to app.yml, updates fine with no issues.
