Hello All, Today, I started getting a bad signature error during my OpenStack installs. My provisioning scripts were working just fine yesterday. I now have to use the --forced-yes switch for my apt-get install -y statements. Otherwise, the Grizzly components fail to install. I do install the ubuntu-cloud-keyring as part of my provisioning script, and I tried did multiple tries with each of following sources: "deb http://ubuntu-cloud.archive.canonical.com/ubuntuprecise-proposed/grizzly main" "deb http://ubuntu-cloud.archive.canonical.com/ubuntuprecise-update/grizzly main" Per blog posts regarding similar errors, i did try adding the following lines to my script, but they didn't resolve the problem either: #apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 5EDB1B62EC4926EA #apt-get update Any help that you can provide would be appreciated, Trevor -------------- next part -------------- An HTML attachment was scrubbed...
