computer that's not connected to internet, I can't validate the public key. The scenario is like this: I download the RPMs, I copy them to DVD. I install CentOS 5.5 on my laptop (it has no internet connection). I try install one using yum (or rpm -i, or whatever). I get the following error: public key for "package" is not installed.

Yum Disable Gpg Check
key not installed Quote Postby apacker83 » 2009/02/23 19:55:35 I am attempting to update my CentOS rpmts_hdrfromfdno nokey system with yum.'sudo yum update' revealed a public key was missing.A post on this forum:http://www.centos.org/modules/newbb/vie ... mpost63026led me to try this:'rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5'which gave me the http://serverfault.com/questions/288648/disable-the-public-key-check-for-rpm-installation prompt back (no errors, no nothing) but 'sudo yum update' gives me the same public key error.So, I tried to use rpmforge which I came across due to Googling:http://dag.wieers.com/rpm/FAQ.php#B2And according to CentOS documentation figured I should enable yum priority handling, essentially following this:http://wiki.centos.org/PackageManagement/Yum/PrioritiesNow, depending on whether I first import the key (RPM-GPG-KEY-CentOS-5), or http://www.centos.org/forums/viewtopic.php?t=12867 install the rpmforge business ('rpmforge-release-0.3.6-1.el5.rf.i386.rpm'), I get different keys that I am missing (either Perl-Crypt Md5 yada yada or nautilus-open-terminal-0.7-3.fc6.i386.rpm)I fear with all of my random attacks I have now completely broken yum. Not to mention I hate yum because on Debian apt-get ALWAYS WORKS NO QUESTIONS ASKED.By the way, 'sudo yum update yum' always yields 'Could not find update match for yum' regardless of what I do.Thus, the following question:1) Can I wipe the slate clean and set up CentOS with the standard CentOS repositories so that 'yum update' followed by 'yum upgrade' will work?2) AND/OR can I stop dealing with this ridiculous yum stuff and get my good old apt-get back??Edited by Moderator - Please keep your language civil. We will not tolerate foul language.

For example, a private key (secret key) locks the package while the public key unlocks and verifies the package. If the public key distributed by https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Security_Guide/sect-Security_Guide-Updating_Packages-Verifying_Signed_Packages.html Red Hat Enterprise Linux does not match the private key during RPM verification, the package may have been altered and therefore cannot be trusted. The RPM utility within Red Hat Enterprise Linux 6 automatically tries https://docs.oracle.com/cd/E37670_01/E39381/html/ol_import_gpg.html to verify the GPG signature of an RPM package before installing it. If the Red Hat GPG key is not installed, install it from a secure, static location, such as public key a Red Hat installation CD-ROM or DVD. Assuming the disc is mounted in /mnt/cdrom, use the following command as the root user to import it into the keyring (a database of trusted keys on the system): ~]# rpm --import /mnt/cdrom/RPM-GPG-KEY Now, the Red Hat GPG key is located in the /etc/pki/rpm-gpg/ directory. To display a list of all keys installed for RPM public key for verification, execute the following command: ~]# rpm -qa gpg-pubkey* gpg-pubkey-db42a60e-37ea5438 To display details about a specific key, use the rpm -qi command followed by the output from the previous command, as in this example: ~]# rpm -qi gpg-pubkey-db42a60e-37ea5438 Name : gpg-pubkey Relocations: (not relocatable) Version : 2fa658e0 Vendor: (none) Release : 45700c69 Build Date: Fri 07 Oct 2011 02:04:51 PM CEST Install Date: Fri 07 Oct 2011 02:04:51 PM CEST Build Host: localhost Group : Public Keys Source RPM: (none) [output truncated] It is extremely important to verify the signature of the RPM files before installing them to ensure that they have not been altered from the original source of the packages. To verify all the downloaded packages at once, issue the following command: ~]# rpm -K /root/updates/*.rpm alsa-lib-1.0.22-3.el6.x86_64.rpm: rsa sha1 (md5) pgp md5 OK alsa-utils-1.0.21-3.el6.x86_64.rpm: rsa sha1 (md5) pgp md5 OK aspell-0.60.6-12.el6.x86_64.rpm: rsa sha1 (md5) pgp md5 OK For each package, if the GPG key verifies successfully, the command returns gpg OK. If it does not, make sure you are using the correct Red Hat public

To obtain and import a GPG key from the public yum repository: Download the GPG key, for example with the the wget command. # wget http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol7 The following are the available GPG keys: http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol7 http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5 http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el4 Check the fingerprint of the GPG key with the gpg command to make sure it matches the key published by Oracle. # gpg --quiet --with-fingerprint ./RPM-GPG-KEY-oracle
