wrong urls in docs ?

[Matthieu Simonin <matthieu.simonin@inria.fr>]

Hello,

I went through the doc lately : 
https://debian-live.alioth.debian.org/live-manual/stable/manual/html/live-manual.en.html

It seems that many urls are wrong : 
e.g https://debian-live.alioth.debian.org/live-manual/stable/manual/html/live-manual.en.html#804
-> they are using the format "protocol://http://..."; which seems problematic and "protocol://..." 
would have been more appropriate.

I can patch if required but the url for getting the git keys are returning a 404 (line 668)

Best,

Matthieu
