-U updating still not working even with --prefer-insecure option...

[artphotodude]

Below is the attached-log. Updating is still not working despite the --prefer-insecure option.
It can now see there is an update, but won't actually download and install it.

Note I rolled back to the earlier version just to show the issue. If I manually, download and install it, it returns an "Up to date" status.

Make sure you are using the latest version: run youtube-dl --version and ensure your version is 2018.02.26. 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 Issues with outdated version will be rejected.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 2018.02.26
