No web clients after many attempts

[dshulman]

Hey, folks.

I’ve installed mopidy and a number of web clients but none of them are showing up under the “Web clients” section of the web server. This is on a pi3 running Ubuntu 22.04 LTS but using the apt repo to get the latest available versions. I’ve tried installing just from apt packages, just via pip, and blended and it just never works.

The logs indicate that the extensions are being detected and loaded. I’ve cranked up logging/verbosity to ‘3’ and the only indication I see of any problem is this:

root@pi30:/etc/mopidy# mopidyctl deps 2>&1 | head
Running "/usr/bin/mopidy --config /usr/share/mopidy/conf.d:/etc/mopidy/mopidy.conf deps" as user mopidy

DEBUG    [MainThread] mopidy.ext Loading entry point: podcast = mopidy_podcast:Extension
DEBUG    [MainThread] mopidy.ext Loaded extension: Mopidy-Podcast 3.0.1

Here’s my current setup:

root@pi30:/etc/mopidy# dpkg -l | grep mopidy
ii  mopidy                               3.3.0-1                          all          extensible music server

root@pi30:/usr/share/mopidy/conf.d# pip freeze | grep -i mopidy
Mopidy-InternetArchive==3.0.1
Mopidy-Podcast==3.0.1
Mopidy-Simple-Webclient==0.1.1

In the above the mopidy package is from apt and the rest is via pip.

Config looks like this:

Just for kicks I upped verbosity to ‘4’, installed Simple-Webclient via pip, and then did a journalctl -u mopidy. I don’t see anything which jumps out as especially odd. There is one thing that is a little surprising in that when I hit the web server I get this amongst the journalctl output:

Jan 20 19:28:04 pi30 mopidy[11398]: INFO     [HttpServer] tornado.access 304 GET /mopidy/ (172.16.2.82) 18.77ms

Now, this is with a clear cache on the browser I normally use and with another browser which has never hit that web server before… notice the HTTP 304 (has not changed since last request)? Maybe there’s something I don’t know about HTTP 304 but that doesn’t seem right.

Thoughts?

After a second look, this is perhaps a bit odd:

Note that Simple-Webclient installed via pip is throwing the error abot reg. While the InternetArchive extension, installed via apt, gets a clean registration (but still doesn’t show up in the web UI client list).

Tried connecting to the process with madbg to see if I could inspect the extension registration information but madbg “dlopen failed”. :\

Simple-webclient is not compatible with Mopidy 3. You should remove it. Ideally the author would state this in their project readme but we can’t control that.

Webclients we know to be compatible with Mopidy 3 are listed at Extensions
