Hi,
Today, after updating my self-hosted Discourse from 3.4.0.beta3-dev to 3.4.0.beta3 via command line, the site is not accessible. It shows Bad Gateway (nginx) page.
May I know what’s gone wrong?
P/s Currently, I have restored my server back to 3.4.0.beta3-dev condition again.
Thanks for any pointer in advance.
The Bad Gateway page will be there for a while, as this happens on my forum as well. Give about 5-10 minutes, it should be alright.
If you see a 504 Timeout error, you can wait a while more and periodically reload te page. At least, that’s what I do. Your forum should be up after that.
Unfortunately I had waited for more than 30 min, still the same.
Hmm… were there any errors in the console when you were switching to 3.4.0beta3?
If I update via console, no error.
But if I update via UI, there was an error, something like the update process failed, and the Reset Update button was not shown.
I tried to update again via UI, and below is the error log:

Spinning up 2 Unicorn worker(s) that were stopped initially
Try a rebuild from the command-line.
I tried already, using:
cd /var/discourse
./launcher rebuild app
The result is Bad Gateway
Also, from the error log, it seems the error is weird:
Docker Manager: FAILED TO UPGRADE
via the UI, you MUST upgrade Docker first before you are allowed to upgrade Discourse, don’t know why it still showed Docker Manager upgrade failure.
Hi, Welcome!
Looks like that is your issue. mini_racer segfaults.
This mini_racer-0.17.0.pre12 version has been introduced at DEV: update mini_racer by SamSaffron · Pull Request #30656 · discourse/discourse · GitHub.
There were several attempts to fix mini_racer previously, from 3.4.0.beta2 to beta4, so I would wait for team feedback before upgrading.
Probably needs a command line update.
Can you tell me more about your server, what kernel is it? What version of docker are you running? What os?
Note this does not look like a segfault to me:
LoadError: /var/www/discourse/vendor/bundle/ruby/3.3.0/extensions/aarch64-linux/3.3.0/mini_racer-0.17.0.pre12/mini_racer_extension.so: undefined symbol: __libc_single_threaded (LoadError)
Likely this is caused cause the actual running container is somehow running glibc < 2.32.
The fix here should be:
./launcher rebuild app
via host.
Thanks.
This fixed my problem.
Note to self: I should not delete my reasonable advice 
My bad and sorry Sam for linking wrongly the PR!
Since OP had rebuilt once, I thought the issue was something else.
