Hi,
I was trying to install a Multimedia application in Debian (Cinelerra), but, when I try to do update, an error about the keyring start in the system, and don't finish that process.
The final error is:

I tried running update, but the error still in the system.

Thanks a lot...

aptitude install debian-multimedia-keyring

googling the first error would have solved it for you, this is a common problem

Thanks a lot again.

PD 1: Sorry for my English. I came from Colombia.
PD 2: I new in Linux, and I have one week trying to fix this.

Best Regards...

Why do you have
etch/stable sources for the main and security repositories
Lenny/testing sources for the Debian-Multimedia repository ?


Notice how all the repositories are pointing at the same branch in my example /etc/apt/sources.list ?

It also looks like your key-rings for main and security repository are out of date..

W: GPG error: http://ftp.debian.org etch Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A70DAF536070D3A1 NO_PUBKEY B5D0C804ADB11277
W: GPG error: http://security.debian.org etch/updates Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A70DAF536070D3A1
W: Couldn't stat source package list http: testing/main Packages (/var/lib/apt/lists/_www.debian-multimedia.org_dists_testing_main_binary-i386_Packages) - stat (2 No such file or directory)

fix your sources list so Debian multimedia is pointing at etch theres a reason all the repositories should match

aptitude autoclean - Get rid of all the packages that are downloaded into your apt cache to prevent conflicts..
aptitude update - Update your sources list again now that the sources are all pointed at the same branch
aptitude install debian-archive-keyring debian-multimedia-keyring - Install the keyrings for the repositories..



See if that helps shake loose your problem..

Hi,
I had to change my sources.list totally, thats mean, I put commentaries in all lines,and that's the way how now look:
"
#
#deb cdrom:[Debian GNU/Linux 4.0 r1 _Etch_ - Official i386 NETINST Binary-1 20070820-20:21]/ etch contrib main

deb cdrom:[Debian GNU/Linux 4.0 r1 _Etch_ - Official i386 NETINST Binary-1 20070820-20:21]/ etch contrib main

#deb-src http://security.debian.org/ etch/updates main contrib non-free

#deb http://security.debian.org/ etch/updates main contrib


#deb http:/www.debian-multimedia.org etch main

"

In this way, are not errors when I run the aptitude autoclean and aptitude update commands.
but, when I run the last command: "aptitude install debian-archive-keyring debian-multimedia-keyring"
This message appear in my screen:

Thanks a lot again for your help...

Is this one of those hidden camera practical joke television programs?

Just in case you're not joking with us, of course there are no errors. Everything that could cause an error is commented out. Obviously nothing will run, but there won't be any errors. Perhaps that is an improvement.

Make your sources.list look like this...
... then follow farslayer's instructions again.

Good Night.
First at all, I'm no joking with anybody, and I know that I need a lot of help.

Thats the way my sources.list look now:
"

Thanks a lot again, and I'll appreciate all your help...

post the output of the following commands please(must be root)

apt-cache policy debian-archive-keyring
apt-cache policy debian-multimedia-keyring
apt-key list
date

it bothers me more that it's not reading the standard and security keys, than the fact that the multimedia keys failed to install.. it looks like your keyring files may be corrupt.. or something

one way to recreate the apt keyring would be the following...

aptitude purge debian-multimedia-keyring
aptitude clean
cd /etc/apt
rm *.gpg
aptitude update
aptitude reinstall debian-archive-keyring
aptitude install debian-multimedia-keyring

Now, I rang your instructions, and are not errors in the messages. !THANKS A LOT FOR THAT!
May I say that this problem could be in one .gpg file?

I'll try to install Cinelerra again...that was how the problem start..
Thanks again.

See you later...

Sweet ! so I guess that was the answer, your gpg apt key file got corrupted somehow.

Glad it's working OK now..

enjoy !!

it solved my problem very well thank your very much..

Glad to have helped.. and welcome to the Forums !!
