Upgraded the server to the latest version. It's gone more purple.

Also, apparently the asset-compile step can fail silently, which then makes the server start but refuse to return any pages.

You can see the errors if you know how to look at the log:
> journalctl -f -u mastodon-web

And if your console has enough lines in it because that's a very long error with the important bit at the top: Can't find an asset in the manifest.

But running the precompile says there's nothing to do:
> RAILS_ENV=production bundle exec rails assets:precompile
> Everything's up-to-date. Nothing to do

Even if you do a clean first:
> RAILS_ENV=production bundle exec rake assets:clean

Ponderous. 🤔

Seems you can force it to actually do the work by removing the manifest:
> rm public/packs/manifest.json

And then it's all like:
> Compilation failed.

Oh. Good. Not going to tell us why then?

Apparently you can ask for more output by editing a line in config/webpacker.yml to
> webpack_compile_output: true

Then you get the overload instead.

I think it was maybe running out of memory?

Free up memory by stopping everything:
> sudo systemctl stop mastodon-sidekiq
> sudo systemctl stop mastodon-streaming
> sudo systemctl stop mastodon-web

And compile assets once more:
> RAILS_ENV=production bundle exec rails assets:precompile

Ahha. If you can read this then that worked.

Restart the services:
> sudo systemctl start mastodon-sidekiq
> sudo systemctl start mastodon-streaming
> sudo systemctl start mastodon-web

And actually reboot to check that it all comes back without more fiddling.
