Like i say, the plugin has been working perfectly, i have run

sudo mopidyctl ytmusic reauth

And it updated my auth.json file with new details from when I set this up, rebooted and stuff, but no difference.

Really hope someone can help/fix

[impliedchaos]

Thanks I'll take a look.

[impliedchaos]

So I checked and this is actually a bug with PyTube which is what we use to break the signature obfuscation. pytube/pytube#1163

They've already got pull requests submitted to fix this, so I'm just going to wait for them to make a new release, then I'll update our code to use the new version, and publish a new release as well. Probably won't take long.

[karl0ss]

@impliedchaos just to let you know, things seeeem to be working again today...

[impliedchaos]

Thanks, that's good to know. Google changes the javascript obfuscation function daily, and it seems like today's doesn't have the code that caused the previous breakage. So I'm still waiting on pytube to implement the fix. Hopefully soon so I can roll out the new release and keep this one from happening again.

[karl0ss]

Ok, thanks for the update, I will let you know if anything changes again here in this thread.

tahnks for your great work.

FYI pytube version 11.0.2 is now out and appears to fix this issue along with an issue that was preventing me from playing any music at all. I would just receive the below error:

Dec 22 18:58:32 dabox mopidy[326566]: WARNING [Core-11] mopidy.core.tracklist Track is not playable: ytmusic:track:5LScCxHS8k8
Dec 22 18:58:32 dabox mopidy[326566]: ERROR [YTMusicBackend-3] mopidy_ytmusic translate_uri error "'NoneType' object has no attribute 'get_signature'"

I ran the following to fix upgrade:
pip3 install -U pytube

[impliedchaos]

Thanks! I'll update to require this latest pytube version and push out a new release.

I'm getting NoneType object has no attribute 'get_signature' errors again with the current obfuscation (I personally noticed songs no longer playing starting today, 2022-01-20, approx 12:00 UTC). I found pytube/pytube#1199 which suggests a small change in pytube.

Manually applying the suggested change in the regex (pytube/pytube#1199 (comment)) in pytube's cipher.py resolved the issue for me for now with pytube-11.0.2 and mopidy-ytmusic 0.3.3

[sprnza]

I've applied the suggested change and it had been working for some time but now it's broken again

[sprnza]

I've also applied a change mentioned here. The error is gone, but playlist is not being populated

[sprnza]

This is the correct fix I suppose, but it still doesn't work with it.

Upd: it does work actually I wasn't able to add some particular playlist but another one has started working.

So basically workaround is:

sudo pip uninstall pytube
sudo pip install git+https://github.com/glubsy/pytube@nfunc_regex_patch

Hi there, I am unable to install pytube@nfunc_regex_patch

I even tried upgraded the pytube to the latest, still I am having the same problem.

Take a look at this issue: pytube/pytube#1289
it solved the problem for me

Worked

[markgaze]

Doing the following fixed it for me 🙂

sudo pip uninstall pytube
sudo pip install git+https://github.com/pytube/pytube@master

(because the branch that was originally used in @sprnza's has now been merged)

This worked for some time, but broke again yesterday :P

same here.

Here's the new fix pytube/pytube#1326 (comment)

I really hope pytube updates with these new fixes soon, because editing sources is getting tiresome.

[mgoltzsche]

Same problem here with pytube 12.1.3.
When I use the latest pytube version 15.0.0 directly (the CLI), the problem does not appear and I can download tracks.
However, mopidy-ytmusic still requires pytube<13 and therefore gets disabled when mopidy starts and the requirement is not met.

I wonder if this is due to my environment since other issues about other problems were created later within this repo, indicating other people don't have the pytube incompatibility problem somehow, do they?

[mgoltzsche]

So how does this work for anyone? I even patched mopidy-ytmusic to use pytube 15.0.0 but it still fails, logging the error:
