I am trying to install WINE onto Raspberry Pi Debian (on raspberry pi). Because they have not got it signed. When I tried doing
, it freaked out and said "Updating from such a repository can't be done securely, and is therefore disabled by default." and it then says "See apt-secure(8) manpage for repository creation and user configuration details". If anyone can help, it would be greatly appreciated! (I just want to install some software, so I'm hoping this is simple and I am dumb!)
