[16:19] <jack> please help
[16:22] <tomreyn> jackyou will need to provide context. the preferred pastebin service is https://paste.ubuntu.com
[16:23] <tomreyn> jack: ^
[16:23] <jack> ok, fine
[16:27] <jack> https://paste.ubuntu.com/p/V2Ry6YH2Qc/
[16:27] <jack> voila
[16:31] <tomreyn> much better. you probably need to identify the ...-dev - packages providing the source code listed there, or just use    apt build-dep xfce4-screensaver
[16:38] <jack> cool, thx
[16:48] <jack> apt build-dep xfce4-screensaver
[16:49] <jack> E: Quellpaket für xfce4-screensaver kann nicht gefunden werden.
[16:49] <jack> :(
[16:49] <tomreyn> you need to add "deb-src ..." lines to your /etc/apt/sources.list
[16:49] <jack> thought apt would be "smarter"
[16:50] <jack> oh? ok
[16:50] <tomreyn> apt thought the user would be smarter
[16:50] <jack> hehe
[16:57] <tomreyn> jack: keep in mind to run   LANG=C   in terminals where you'll gegenerate program output you want to share with english speaking support volunteers.
