Debian :: Update Error - Public Key Not Available?
Jun 13, 2011
I have added the following line in sources.list, deb [URL] squeeze main non-free
Running apt-get update i get this error message,
Reading package lists... Done
W: GPG error: http://www.debian-multimedia.org squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 123456789
Do i need to generate this public key 123456789 ? If so, how?
Running apt-key update has not solved the problem.
apt-get install debian-archive-keyring was a recommended solution from some googling.
I have also read this page, [URL] , but how to add a key is under construction.

I turned on my debian systems. Update tells me that I have 26 updates, mostly to samba. I proceed and it gives me an error saying something about public key not available. Suggests to try smart update. I do that, smart update says I have 129 updates available (reasonable I guess b/c I have not updated in close to a year)
I proceed with smart update...now it says I can install 137 updates, I hit Check, tells me it is downloading packages, then, I get an error:
W: GPG error: http://code.highrise.ca lenny Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B95C4D3ECC4D3D27
I don't understand why....What is the solution for this?

How can I forward all traffic from a public IP to another public IP. Let's say I have a first debian box named box1 with eth0 = 1.1.1.1 and eth0:1 = 1.1.1.2 and I want to forward all traffic from 1.1.1.2 to "box2" located somewhere else over the internet and having for eth0 2.2.2.2 Both 1.1.1.0/24 and 3.3.3.0/24 are public IP ranges.

I have a very strange problem; when trying to apt-get update or aptitude update I get time out errors. At first it was resolving ipv6 adresses:
Cannot initiate the connection to ftp.litnet.lt:80 (2001:778::87). - connect (101: Network is unreachable) [IP: 2001:778::87 80] Err [URL] Cannot initiate the connection to security.debian.org:80 (2001:a78:5:1:216:35ff:fe7f:6ceb). - connect (101: Network is
unreachable) [IP: 2001:a78:5:1:216:35ff:fe7f:6ceb 80] As my host does not have normal ipv6 support, i just tried to disable ipv6: echo net.ipv6.conf.all.disable_ipv6=1 > /etc/sysctl.d/disableipv6.conf

The public key isn't available when I try to use the Update Manager; clicking the "Check" button results in a popup with the following text:
Code:
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6E871C4A881574DE
I tried adding the public key via:
Code:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 6E871C4A881574DED
Is that the right code to enter? Because when I did that it didn't fix the problem.

I have to manage a publicly accessible computer, and people know the password and are willing to click just anything, that pops up and has a "yes"/"ok"/"i agree" button on it, just to make the message disappear. (yes, I hate their ignorance ...) As long as they can use the net, that is all they care about...
My question is, can I still get updates for Maverick without being prompted for upgrade to Natty? Also I would like to remove the button from Update Manager. Is there a simple way to do that?

I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive

I run the following file with the >log.log redirector and it does not capture errors.
#!/bin/bash
echo ************************BEGIN LOG******************************
date +"%m/%d/%Y %H:%M:%S $HOSTNAME"
cp -f /scripts/original/clamscans.log /scripts
[code]....
The following errors show up when I run from the file from the term window, but are not written to log.log:
tar: /public/public/clamscans/*.txt: Cannot stat: No such file or directory
tar: Error exit delayed from previous errors
mv: cannot stat `/public/public/clamscans/*.txt': No such file or directory
I know with windows you can add the 2>&1 to capture error data. Is there such a thing for Linux?

My computer: 3 year old cheapish box, Gigabyte board with onboard video and sound. Cat5 cabled to Linksys wired router to a cable modem. Debian 6.0 Stable. Network installation.
This didn't happen from the initial installation but I now get an error message each time I get the updates.
I first see the red update notification icon top right of Gnome desktop. I click on it, enter root password at prompt. Click the install updates button on the update manager window. The software progress bars show me the download progress but then I get the following errors.
An error has occurred and installing has been aborted. Error Message: subprocess installed post installation script returned error exit status 1
Error message: dependency problems - leaving unconfigured.
I cancel the messages. The notification icon then turns to the reboot icon. If I start the update manager again from the System menu it shows me that my system is up to date, so I suspect the update has taken place. But why am I getting the error messages. This now happens every time I see the new updates icon. Apart from that everything works fine.
I include my source list in case this helps.

I'm sometimes getting a 'duplicate source' error when I update, but not always. Sometimes it's just fine, without me having changed anything significant. To be honest I don't really understand what's going on.
Here's my sources.list :
deb [URL] testing main
deb-src [URL] testing main
deb [URL] testing main contrib
deb-src [URL] testing main contrib
deb [URL] testing main non-free
deb-src [URL] testing main non-free .....
Whats with the duplicate sources referring to /var/lib...? I've never touched that directory. Ever. And why are there three 'duplicates' of testing/main when clearly I only have two in sources.list? I'm confused. Is my sources.list set up properly? Usually, running another update immediately after the first one cleans up the errors, but this keeps coming back every few days.

I have trouble with rsa authentication:
I did create an rsa certificate with ssh-keygen using my root account on a client: ssh-keygen -t rsa -b 2048 no passphrase I did copy the rsa pub_key from my client to the server scp id_rsa sampleuser@sampleserver:/home/sampleuser/.ssh/authorized_keys
I did change the ownership to the "sampleuser" of the pub key file on the server: I trayd to connect:
ssh sampleuser@sapleserver
I get that: permission denied (public key)... I know I do smth wrong but I don't know what.

I have done a update from Lenny to Squeeze with the update manager within Gnome. And there was a error 126 and the update broke off leaving me with a non working system. The system does start into Debian Squeeze to the command line. Users are in place and a login is possible. X does not work and there a lot of broken and defect packages. I want to repair my system. Is a restore without losing the configuration possible?

I've got Opera for Linux on my Debian Lenny system, installed by adding their repository to my APT config, and it works great. Just recently there was an update. When I downloaded it, it could not install because the signature could not be verified.
W: GPG error: [url] lenny Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F9A2F76A9D1A0061
Why would that happen now when I already had the repository correctly setup in my apt files? I tried re-installing the key and that didn't change anything. Is there a problem with a public key server somewhere?

I migrated to Debian sid, but since then I got this error everytime I launch Update Manager (whether it's in graphical mode or from a shell). Just after putting down my root password, I got this error:

On my stable/squeeze computer, I have /etc/ssh/ssh_host_rsa_key.pub but I cannot find this in my testing/wheezy computer. Why can't I find it? Did the way to retrieve one's public rsa key change? I have openssh-client and openssh-server installed on both computers.

I am very new to encryption. Right now I am making certs and keys using RSA public-key cryptography. Is RSA the best? What other public-key cryptography <?> is there to use? Is <?> a cipher or algorithm? Whats the difference?
