Make sure you are using the latest version: run youtube-dl --version and ensure your version is 2019.01.27. If it's not, read this FAQ entry and update. Issues with outdated version will be rejected.

• I've verified and I assure that I'm running youtube-dl 2019.01.27

Before submitting an issue make sure you have:

• At least skimmed through the README, most notably the FAQ and BUGS sections
• Searched the bugtracker for similar issues including closed ones
  --> found #14607 but there was no solution or usefull hint. I tried option --restrict-filenames but it gave youtube-dl: error: no such option: --restrict-filenames.
• Checked that provided video/audio/playlist URLs (if any) are alive and playable in a browser

What is the purpose of your issue?

• Bug report (encountered problems with youtube-dl)
• Site support request (request for adding support for a new site)
• Feature request (request for a new functionality)
• Question
• Other

It starts downloading the playlist but stopps on video 6 of 17. Maybe due to German umlaut in title. This is on Raspbian.

Most likely your fs does not support this.
And it's --restrict-filenames without trailing dot.

[ABihler]

The --restrict-filenames option actually works. Thanks for the hint. There was a copy paste error in the command.
