There have been a couple of reports of a similar error recently:
[Cannot build on arm, Zlib::BufError during assets:precompile](https://meta.discourse.org/t/cannot-build-on-arm-zlib-buferror-during-assets-precompile/309300)
[Rebuild fails when these plugins are present](https://meta.discourse.org/t/rebuild-fails-when-these-plugins-are-present/310455)
Not sure if an exact cause has been found, but one was thought to be Animated Avatars and the other Subscriptions (though Subscriptions has been rebuilding fine for me).

I do use MaxMind, so maybe [that might be the issue](https://meta.discourse.org/t/cannot-build-on-arm-zlib-buferror-during-assets-precompile/309300/5). I also commented out the non-Discourse plugin. That didn’t solve the issue, so I don’t think it is due to a non-official plugin.
I also rebooted the container host, no effect on the build outcome. In the past a networking issue was resolved by a reboot.

Did you try rebuilding without it?
My best explanation for this right now is some spurious error with Maxmind. But looking again at some of the errors that doesn’t make sense either.

I’ve just had this issue when updating a Discourse install…
I believe the cause is because when `DISCOURSE_MAXMIND_LICENSE_KEY` is specified in the `.yml` container file without a corresponding `DISCOURSE_MAXMIND_ACCOUNT_ID`.
@tgxworld’s pull request adds the use of `DISCOURSE_MAXMIND_ACCOUNT_ID` in multiple places and explains the need for “Account ID”:
[https://github.com/discourse/discourse\_docker/pull/796](https://github.com/discourse/discourse_docker/pull/796)
For me the fix was adding `DISCOURSE_MAXMIND_ACCOUNT_ID` and rebuilding (I rebuilt twice, but this was most likely a temporary issue).

A recent rebuild worked fine. If it fails again I’ll have a look at @DeanMarkTaylor his suggestion. Thanks everyone!

FWIW I just hit the `Zlib::BufError: buffer error (Zlib::BufError) ` rebuild error and adding in the `DISCOURSE_MAXMIND_ACCOUNT_ID` and rebuilding went through first time for me. 👍

Same here. Adding the account ID and rebuilding is working again. 🙂

When the 3.3.0.beta3 version was released, I got this error inconsistently; it failed once, and then the rebuild succeeded. (Not having found this post, I worried about memory corruption! 😬) Tonight, doing a rebuild, it consistently failed until I found this post and added `DISCOURSE_MAXMIND_ACCOUNT_ID` to the existing `DISCOURSE_MAXMIND_LICENSE_KEY` and then it reliably succeeded.
(I assume something like that maxmind rolled out a change with a blue/green deployment and that earlier I hit different versions of a back end service each time…)

Rebuilding just failed because of MaxMind lines. It worked until now, and without any changes in app.yml it failed now. So something bigger is broken.
What ever, I don’t need it under Discourse, so I let it be commented. But it is totally sure the issue is something else than just account\_id.

Agreed. My rebuild failed even with `DISCOURSE_MAXMIND_ACCOUNT_ID` set in app.yml.
As soon as I commented out all mention of Maxmind, the rebuild succeeded.
