Deluge displays blank screen.

[Simmy]

Hello,
I've had deluge installed inside a docker container on Debian 10 for some time.
Two days ago I lost access to the WebUI (Being greeted with a completely blank white page, not even settings), I tried reinstalling and everything in between. Even a fresh install on another server, with again the same issue.
I have since realised that deluge was updated at the same time.

Am I missing something obvious?
Is this something easily solved?

Regards.

Hi.

In your case, this https://github.com/linuxserver/docker-deluge/issues/127 might help.

I don't use docker, but my deluge install on Ubuntu 18.04 has been behaving the same since it updated yesterday to 2.0.4.
I've checked everything I could think of, configs-wise, but nothing made a difference.
I'm still trying to figure out a way to revert to 2.0.3 (not hugely at ease with linux), so all I can say is other people on docker in that ticket seem to have had success by reverting.
I will add, from what I have tried so far on my install, the problem presents pretty much exactly as on that docker ticket.
The only difference is I have a few plugins active and the errors on the browser console would be related to them, at first. But I can connect to the daemon on a 2.0.3 thin-client in another (windows) machine and everything seems to be running as it should, apart from deluge-web. So I disabled the plugins, reloaded deluge-web and then I got the exact same error as in the second screenshot of that ticket: an error on the line that reads "Deluge.debug = false;".
The backend, as it were, for deluge-web seems to be working, because the extension I use to send torrent/magnet links works and adds them successfully. So, as far as I can tell/have tested, it's doing all it should, except displaying the webpage as usual.
The only thing I haven't tried is switch python versions. I'm running 3.7.5, but I believe 3.8 is also installed. I'd rather not have to change defaults because other programs could break.

Can anyone confirm whether this could be setup dependent, or an actual bug with deluge-web?

In any case, thanks in advance.

[Cas]

Hmm it must be a bug in WebUI, I shall have to look into it. Are there any error in the browser console?

[ftpgetter]

In my case after update to 2.0.4 file deluge-all.js was 0 size. Chrome devtool show error in line 42 of index (Deluge.debug = false;)

I just copy content of deluge-all-debug.js into deluge-all.js and UI show again.

Thanks for the reply.

I have deluge going through a reverse proxy in apache, and the "base" is probably correctly being passed to deluge, because I have it set as "/" on web.conf, but it is correct in the page config section, here. If I try the address as ip:port, the same blank page shows up and "base" is indeed "/" since it's not going through apache. I mention it only because it was one of the first things I thought of and tested.

As for the errors with the page here is the output:

Code: Select all

I don't know if it's too readable as pasted, but essentially each plugin seems to fail at the line starting with "Deluge.plugins.ExecutePlugin =", whereas ext-base.js shows up as a long line of code, with the error highlighting a section that reads "N=P.prototype;".
In fact, I just noticed I get the same error as the first screenshot in the docker example with label.js line 433, so there's probably some commonality there.

If I disable the plugins, like I mentioned before, all I get is an error at the line "Deluge.debug = false;" of the page source, like in the second screenshot of the docker example. Just tried it and it's the same "Deluge is not defined" error at the same location as in the screenshot, line 41.

If there's something you want me to try, I'll gladly do it, if my skills are up to the task

In my case after update to 2.0.4 file deluge-all.js was 0 size. Chrome devtool show error in line 42 of index (Deluge.debug = false;)

I just copy content of deluge-all-debug.js into deluge-all.js and UI show again.

Indeed that worked! Thank you!
Strange mishap, but yeah, both files existed with same creation time, but deluge-all.js was size 0.

I can confirm it's a problem with the packaging of 2.0.4 where it seems to have been a error with minifying the javascript files.

You should be able to check by appending debug option to url:

Code: Select all

localhost:8112?debug=1

[jsw10471]

So I can confirm this issue with the recent version in Docker Container as well.

You can use the following command to access your container and make the change within it:
docker exec -i -t <container-name> /bin/bash

Then run this command from within the container:
cp /usr/lib/python3/dist-packages/deluge/ui/web/js/deluge-all-debug.js /usr/lib/python3/dist-packages/deluge/ui/web/js/deluge-all.js

I'm not using docker, but just an ordinary install on Ubuntu 18.04 that's been working great for years (thanks @Cas and team!)

But the above cp command fixed things for me too. Thanks @jsw10471 for the troubleshooting!

[Cas]

Thanks AzureRaptor, I looked into how the Docker deluge was installed and it uses the Ubuntu PPA which in the build process minifies the js files with closure-compiler resulting in an error and zero-length deluge-all.js.

Now I fully understand the issue I have fixed it and have a release pending...

Edit: 2.0.5 released
