From: Nicolas Braud-Santoni Date: Sun, 11 Feb 2018 11:01:56 +0000 (+0100) Subject: Remove upstream's autoupdate mechanism X-Git-Url: https://git.rapsys.eu/youtubedl/commitdiff_plain/1f17a37b9b95db09a420a1f52cf18723ce4eb8b5?ds=sidebyside;hp=68a5583f34cad0cbaf50fa60ad5c6f8c934d0f1b Remove upstream's autoupdate mechanism The autoupdate function is defunct on Debian anyway, and the signature validation code is fairly sketchy.
