Static assets stopped working suddenly

[peterbe]

I haven't used pghero for a couple of weeks and checked in today. It loads fine but the .js and .css are 404'ing. I can curl it just fine, on the server, like this:

curl http://localhost:6000/ | less

And it gives a regular pghero HTML thing and at the top it mentions:

...
    <title>PgHero / Overview</title>
    <meta charset="utf-8" />
    <link rel="stylesheet" media="screen" href="/assets/pghero/application-c2618b70600dfedb0f3ba1f916d97a2f93a3f265aba10356abb763bd663d0cbd.css" />
    <script src="/assets/pghero/application-3807e140de3bf52364d575c9c1cba1ed730999b53e2781da4bf8bb15b01791bf.js"></script>
...

But those assets don't work. E.g.

# curl -v http://localhost:6000/assets/pghero/application-3807e140de3bf52364d575c9c1cba1ed730999b53e2781da4bf8bb15b01791bf.js

It's been a while since I installed this on Ubuntu 16.04 DigitialOcean server. I think I followed these instructions: https://github.com/ankane/pghero/blob/master/guides/Linux.md#ubuntu-1604-xenial

I don't know what version I have installed but the package has a version:

# apt show pghero

Also, I'm not entirely sure how else to find information about my installed version:

root@songsearch-1473901544357-2-2gb-nyc1-01:~# pghero --help
Usage:
  pghero run COMMAND [options]
  pghero scale TYPE=NUM
  pghero logs [--tail|-n NUMBER]
  pghero config:get VAR
  pghero config:set VAR=VALUE
  pghero configure
  pghero reconfigure
root@songsearch-1473901544357-2-2gb-nyc1-01:~# pghero logs

Hey @peterbe, it looks like you're on the latest version (2.0.4). My hunch is PgHero was updated without being restarted. Try running:

sudo service pghero restart

[peterbe]

That certainly did the trick. Now it works. I'll leave it to you to decide whether to keep this as an issue or if you want to ping the debian packagers. :)

The upgrade instructions in the readme include the need to restart, so think that's fine for now.
