[Gnewsense-dev] Troubles with getting development environment set up

[Harry Prevor]

For some reason after following the directions at 
<http://www.gnewsense.org/Packaging> word-for-word I still get these GPG 
errors upon apt-get updating:

> W: GPG error: http://http.us.debian.org squeeze Release: The following 
> signatures couldn't be verified because the public key is not 
> available: NO_PUBKEY AED4B06F473041FA
> W: GPG error: http://security.debian.org squeeze/updates Release: The 
> following signatures couldn't be verified because the public key is not 
> available: NO_PUBKEY AED4B06F473041FA

I have debian-archive-keyring installed and up-to-date. To make matters 
worse, whenever I do apt-get upgrade now, I'm prompted to upgrade these 
packages: firmware-linux-free libapache2-mod-php5 libmodplug1 
libruby1.9.1 libtiff4 libtiff4-dev libtiffxx0c2 linux-base 
linux-libc-dev php-pear php5 php5-cli php5-common php5-gd php5-mysql 
php5-sqlite. They all seem to be from the Squeeze repository, despite my 
/etc/apt/preferences rules. Here is my /etc/apt/sources.list:

> deb http://us.archive.gnewsense.org/gnewsense-three/gnewsense parkes 
> main
> deb-src http://us.archive.gnewsense.org/gnewsense-three/gnewsense 
> parkes main
>
> deb http://us.archive.gnewsense.org/gnewsense-three/gnewsense 
> parkes-updates main
> deb-src http://us.archive.gnewsense.org/gnewsense-three/gnewsense

> deb http://us.archive.gnewsense.org/gnewsense-three/gnewsense 
> parkes-security main
> deb-src http://us.archive.gnewsense.org/gnewsense-three/gnewsense

> deb http://jxself.org/repo/freesh/ freesh main

> #deb http://backports.debian.org/debian-backports squeeze-backports 
> main
> #deb http://backports.debian.org/debian-backports/ 
> squeeze-backports-sloppy main
>
> deb http://mozilla.debian.net/ squeeze-backports iceweasel-release

And here is my /etc/apt/preferences:

> Package: *
> Pin: release n=squeeze
> Pin-Priority: -1

Any idea what's going on here, how to fix it, or if it is even a 
problem?
