The following signatures were invalid: BADSIG 40976EAF437D05B5

I would get this error whenever I would run ‘sudo aptitude update’ or ‘sudo apt-get update’:

W: GPG error: http://mirror.anl.gov oneiric Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>

I was able to resolve this issue for this GPG public key in particular by doing the following:

sudo apt-get clean
sudo mv /var/lib/apt/lists /tmp
sudo mkdir /var/lib/apt/lists
sudo apt-get update

vpnc on Ubuntu Oneiric: “Error: either “to” is duplicate, or “ipid” is a garbage.”

When one attempts to connect to their VPN after installing and configuring vpnc on Ubuntu Oneiric, the following error occurs:

root@ubuntu:~# vpnc-connect 
Error: either "to" is duplicate, or "ipid" is a garbage.

After some time it eventually times out and fails to create a connection.

vpnc version information:

It appears that the Ubuntu package vpnc comes with an old version of vpnc-script. This script is what sets up all the addresses and routes for you. The OpenConnect project provides an updated / revised release of this script. Download the latest copy from here . Replace the vpnc-script script that comes with the Ubuntu vpnc package: /etc/vpnc/vpnc-script.

Installing Sun Java Non-interactively

In order to install the Sun Java packages on Debian or Ubuntu, you must first accept Sun’s license. Normally you are suppose to do this through an interactive menu. In order to get around this license prompt you can accept the license prior to installing the package.

Create a file containing the following lines:

sun-java5-jdk shared/accepted-sun-dlj-v1-1 select true
sun-java5-jre shared/accepted-sun-dlj-v1-1 select true
sun-java6-jdk shared/accepted-sun-dlj-v1-1 select true
sun-java6-jre shared/accepted-sun-dlj-v1-1 select true

Then run /usr/bin/debconf-set-selections as root. Now you should not be prompted to accept the license anymore.

Replace Drive

Power down the server and replace the failed physical drive.

Add new Drive to RAID

Verify current partition information

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes:  dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)

If the drive you replaced contains the boot partition, you need to make it bootable by Grub once again.

Use this list on another system to set what to install

sudo dpkg --set-selections < installed-packages.txt

Perform the installation. Type ‘I‘ and allow dselect to install of the the packages listed in your list. When it’s finished, type ‘Q‘ and hit the ENTER key to exit dselect.

sudo dselect

If you just want a clean list of installed packages

dpkg --get-selections | grep -v deinstall | cut -f 1 > installed-packages.txt
acpi-support
acpid
adduser
adium-theme-ubuntu
aisleriot
