Ubuntu :: Getting Lots Of Errors - Signatures Couldn't Be Verified Because Public Key Not Available

Mar 3, 2011

When I try to install things I am getting lots of errors.

[code]...

What can I do to fix my problems? I also included a screen shot of the repositories in Software Sources. I been messing with BeachBit as Root and been toying with Ubuntu Tweak and so I think I messed something up on accident. Here is my list that I have too.

[code]...

Some index files failed to download, they have been ignored, or old ones used instead.

Ubuntu Installation :: Update Manager Wants A Command Line Verified?

Aug 27, 2010

I made a live USB memory stick / pendrive with Ubuntu netbook remix 10.04 using my desktop computer. I want to install / update my netbook that has no network function yet. I booted the desktop with the pendrive & ran update manager. I want to update the kernel so I will have the driver that will operate my netbook ethernet.Acer AOD260 has Ethernet Controller: AR8151 v1.1 Fast Ethernet, Atheros Communications & Network Controller: Broadcom 4727 (rev 01)and will not work from the current release of 10.04 (too new) but there are supposed to be drivers in the newer kernels.

Running Update Manager I get a box labeled "Debconf on ubuntu" & says "Configuring grub-pc". There is an entry box that says "linux command line:" & is empty. When I press the help button I get the message "The following Linux command line was extracted from /etc/default/grub of the 'kopt' parameter in GRUB Legacy's menu.lst. Please verify that is correct, and modify it if necessary.The installer is hanging, Preconfiguring packages ..., probably waiting for a response, but I have no idea what to do.

If you mess up so what format start over.

Debian Installation :: Why Torrent File And Checksums / Signatures Are HTTP

Debian Installation :: Apt-get Update Or Aptitude Update - Error "Cannot Initiate The Connection To Security.debian.org:80"

Jul 14, 2011

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:

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.

Debian :: Error Message At Each Update?

Sep 6, 2011

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.

# deb cdrom:[Debian GNU/Linux 6.0.1a _Squeeze_ - Official i386 NETINST Binary-1 20110320-15:03]/ squeeze main

Debian :: Getting Duplicate Source Error When Update

Apr 15, 2011

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.

Debian Installation :: Update To Squeeze Failed - Error 126

Dec 21, 2010

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?

Debian Configuration :: Error In Opera Update From Repository

Jul 2, 2010

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?

Debian Configuration :: Error - Could Not Update ICEautority File /var/lib/gdm3/.ICEauthority

Aug 8, 2010

Today I tried to attach my digital turntable to the line-in of the computer and hoped for some sound to come. Unfortunately it didn't work. I switched the line-in feature on and put the volume on max. Still no results. I checked the same on Windows and this DOES work, so it can't be the hardware. Do I have to install some extra app in order to use the line-in in put? To complete the information: I'm using Squeeze 64-bits with Gnome. The turntable (Akai ATT05U) HAS worked before (that was when I used Ubuntu 32-bits on an Intel Celeron ). Another thing: since I tried to edit the sound settings, I get an error message at boot: "Could not update ICEautority file /var/lib/gdm3/.ICEauthority". Does this have anything to do with the audio matter?
