I just had the oddest experience doing a simple reboot of my Amazon Lightsail instance. Did the reboot… waited for restart. Got “502 Gateway Error - Nginx” error message screen on some (I assume uncached) pages). Waited a bit… Did a discourse rebuild via shell. Got an error message that rebuild fa…

It’s hard to tell from your description. What errors are you getting when you rebuild?

I try another update soon and update this. I didn’t save the log file and running updates spikes my burst zone pretty badly (especially after running it 3 times), so I needed to wait a day or so to get my burst levels back up.

This seems to be the culprit. Seeding default *** Bundling assets. This will take a while *** $ RUBY_GC_MALLOC_LIMIT_MAX=20971520 RUBY_GC_OLDMALLOC_LIMIT_MAX=20971520 RUBY_GC_HEAP_GROWTH_MAX_SLOTS=50000 RUBY_GC_HEAP_OLDOBJECT_LIMIT_FACTOR=0.9 bundle exec rake themes:update assets:precompile Updat…

And now my forum is completely down and 500 erroring. :frowning: Why would that happen? I would have thought the update only replaces the current working forum once the process is finalized and doesn’t run into issues?

But isn’t dark a system theme component? How could a system theme component be causing that kind of issue? But thanks I will probably be able to fix the issue now that I know what’s going on.

The theme component is deprecated and Discourse refuses to use it. BUt if you do a ./launcher rebuild app then it takes down the container to build the new one (because it’s using the same database files). If the build fails, then you need to restart the container to get it running again.

Yeah I noted the update actually was complete on all the other elements once I deleted the Dark and Alternate Logos components everything was updated in the update screen.

我不了解你最初的问题，但这是你当前的问题：Failed to Bootstrap, due to discourse-alt-logo theme component

你应该能够

./launcher start app

然后删除有问题的主题组件。
