I used to be able to run the command:
youtube-dl.exe -U
To update youtube-dl. But now, it says:
ERROR: can't find the current version. Please try again later.
As always when an error message of any kind, anywhere, tells you to "try again later", it never works later. It's permanent. That's like a law of nature.
I have searched for this and found discussions about it. Those discussions, however, don't actually offer any kind of real explanation/solution. Which is also like a law of nature whenever I have any computer issue; nobody knows how to fix it, and it just happens for seemingly no reason and without me ever doing anything to provoke it.
youtube-dl.exe --version
Gives:
2020.07.28

youtube-dlexecutable version (youtube-dl.exe) from version2020.07.28to2020.09.06using-Ujust today. So this appears to be working, at least in some instances. My thoughts would be that this was perhaps a temporary issue with the update servers or there is/was some connection issue perhaps on your end. – Anaksunaman Sep 10 '20 at 19:14
