Repository
This repository is mostly for Debian unstable (Sid) and experimental branch, but some of packages may also work on testing (currently Wheezy). Only two architectures are provided (i386 and amd64), but there are sources repositories too. To use my PPA add these entries to your sources.list:
Unstable:
deb http://hadret.rootnode.net/debian/ unstable main deb-src http://hadret.rootnode.net/debian/ unstable main
Experimental:
deb http://hadret.rootnode.net/debian/ experimental main deb-src http://hadret.rootnode.net/debian/ experimental main
GPG Key
Here's little something for secure-apt:
gpg --keyserver subkeys.pgp.net --recv-keys EE903351 gpg --export -a EE903351 | apt-key add -
Or in one command:
wget -O - http://hadret.rootnode.net/debian/duckbill.key | apt-key add -
Remember that you need to be root to properly add GPG key.
When HDPPA was making itself public for the first time, I was using time-limited public key (0x433E270B/duckbill-old.key) and I had to move to the new one before expire date (2011-02-08). You can read more about transition in this post on my blog.
