I found the solution by myself in the log file /var/log/apache2/error.log: There the error message "/ usr / bin / youtube-dl: not found" was included. According to the instructions above, youtube-dl is installed in / usr / local / bin / youtube-dl. I solved it by creating a link "ln -s / usr / local / bin / youtube-dl / usr / bin / youtube-dl".

It is unclear to me why youtube-dl is no longer found in the / usr / local directory. I have already observed this with other programs. I run Nextcloud as LXC under Proxmox. I suspect something has changed in one of the last updates, which means that / usr / local is no longer read.

I still have this same issue with NC and ocDownloader with youtube-dl installed with snap on an CentOS 8. If I start /snap/bin/youtube-dl https://path.to.the.video in the linux shell, all works fine. Any idea?

[hifihedgehog]

Can confirm. Latest release of ocdownloader does not interface properly with youtube-dl. I can download YouTube fine with youtube-dl in terminal. ocdownloader, with ocdownloader’s latest, can’t is the problem.

old version youtube-dl cannot found the right url i think , try to upgrade youtube-dl . if the error exists, maybe because the youtube-dl you upgrade is not the target that ocdownloader use, i have three python with different version which also have three copy of youtube-dl . Simple way is to upgrade all youtube-dl version in any python environment on your devices. try pip install --upgrade youtube-dl ; pip2 install --upgrade......; pip3 install --upgrade...... ;

Hello, I have got the same issue with the following configuration (the real youtube-video-url could not be found):

Centos 8 Server with snap (updated with yum update) nextcloud snap package (updated to the newest available) youtube-dl snap package (updated to the newest available) (snap refresh)

Could someone please help me to configure the path to work for youtube-dl inside the nextcloud plugin ocdownloader with this configuration? Thanks in advance :)

regards, NerdSnapper

If it is resolved, it need to be informed how to do it..? Any solutions?

[NerdSnapper]

I tried to start the youtube-dl by hand from /var/lib/snapd/snap/youtube-dl/2846/bin

It gaves me the following error: ERROR: unable to open for writing: [Errno 30] Read-only file system: 'Alizée - Moi... Lolita (Live 2020)-NhbyuiHPg4.f137.mp4.part'

I am still not knowing, what to change for using youtube-dl with my configuration.

[NerdSnapper]

Does someone know a solution to use ocdownloader with youtube-dl in NC? There is no change in the issue since Sept 2020, maybe there was posted a solution anywhere else? I did not find any...

On my system, everything is the newest snap (nc, youtube-dl and snap itself)
