|Re: [PLUG] First attempt at creating a customized Live CD|
Eric,You are correct about the signing key. To find the one you want let's use LibreOffice as an example...
Go to the PPA's site on Launchpad https://launchpad.net/~libreoffice/+archive/ppa Then click the link "Technical details about this PPA" There you will see the signing key. Note:If you are in a fully chrooted LiveCD environment you can use the following to add the PPA and the key as well. Then apt-get update, etc.
add-apt-repository ppa:libreoffice/ppaThe details of this command (the name of the PPA not the syntax) are on the Launchpad site as well. add-apt-repository is not in the server version of Lucid. You have to install it.

Hi all, I have been trying to follow the instructions here for creating a custom Live CD: https://help.ubuntu.com/community/LiveCDCustomizationFromScratch In the Make the ChRoot Environment (https://help.ubuntu.com/community/LiveCDCustomizationFromScratch#Make the ChRoot Environment) it says: <quote> You may edit the sources.list in the chroot to add a line from a PPA, if you need. You will need to add the PPA's key to your chroot's package manager. On the PPA's overview page you'll see the PPA's OpenPGP key id. It'll look something like this: 1024/12345678. Copy it, or make a note of, the portion after the slash, e.g: 12345678. This key will be added once we enter the chroot. Important: Make a backup copy of /sbin/initctl this next step will delete this file. There is a problem with 10.04 upstart package not containing /sbin/initctl.distrib and even after you update upstart the directions for leaving the chroot do not seem to restore this file. sudo chroot chroot mount none -t proc /proc mount none -t sysfs /sys mount none -t devpts /dev/pts export HOME=/root export LC_ALL=C sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 12345678 #Substitute "12345678" with the PPA's OpenPGP ID. </quote> My question is about the last line where it says " Substitute "12345678" with the PPA's OpenPGP ID." It seems to say that with the assumption that you actually know what a PPA OpenPGP ID is. I realize it has to do with signatures for repositories, but I do not have the slightest idea where to get it. I have added a couple repositories to sources.list, but they should have been included when I did the copy of sources.list into chroot/etc/apt. Can someone tell me what I need to fill in for the OpenPGP ID or where to get it.
