Youtube-dl download error

[rahdabas]

Hi. I recently reinstalled my Linux System and tried using youtube-dl as usual but got this error:

youtube-dl -wt http://www.youtube.com/watch?v=XbGs_qK2PQA
[youtube] Setting language
[youtube] XbGs_qK2PQA: Downloading video webpage
[youtube] XbGs_qK2PQA: Downloading video info webpage

KeyError: 'sig'

Did I do something wrong here?
I tried reinstalling but the same error is returned.

You're probably running a (really) outdated version (run youtube-dl --version to find it), that error appeared at the start of the last summer, and it was fixed soon after that. You'll have to update with sudo youtube-dl -U or using the package manager of your distribution.
In general, we prefer to get the output with the --verbose option (like youtube-dl -wt http://www.youtube.com/watch?v=XbGs_qK2PQA --verbose), which gives us info about the version, operating system and other stuff we may need.
Anyways, thanks for your report. If you have any problem, just ask or open an new issue if it's unrelated.
