Consider the following scenario. You have downloaded the CentOS-7-x86_64-Everything-1511.iso from the CentOS Project or a mirror, used the ISO to create a VM in VMware Workstation, and now want to be able to access a package repository (repo) when you have no Internet access. Assume that a GNOME desktop is available on your CentOS VM and the VM is sized such that you have at least 8 Gb of free disk space. Copy the IS0 to your CentOS VM by whatever method works for you. If you have VMware Tools installed, you can just drag and drop the file using
If you encounter any of the following messages: rpmdb: PANIC: fatal region error detected; run recovery error: db3 error(22) from dbenv->open: Invalid argument error: cannot open Packages index using db3 – Invalid argument (22) error: cannot open Packages database in /var/lib/rpm error: rpmdb: damaged header #1439 retrieved — skipping. or a similar RPM-related error message, it is probable that your RPM database is damaged. RPM uses a database to maintain the package dependency information. This database is normally located at /var/lib/rpm. # cd /var/lib/rpm # ls -al total 86420 drwxr-xr-x. 2 root root 4096 Nov 18 21:09 . drwxr-xr-x. 45
In previous posts I examined the internals of RPM packages and the RPM database itself. In this post, I explore how to trace RPM package installation, update and removal on Linux distributions which use YUM (YellowDog Update Modified). If you examine /var/log/yum.log, an example of which is shown below, you will note that the date component of each entry includes the day and month but not the year.

The latest version of RPM (4.10) that was recently released supports dpkg-style tildes (~) in version/release strings. The tilde character can be used to append a label such as “beta” to a package without actually incrementing the version of the package. For example – package-1.0~beta. In this case, the package package-1.0~beta would not replace package-1.0 as the former package is considered to be an older version, even if it was released later. See here for more information.
So you want to get Adobe Flash working on Firefox in Fedora 17? Here is a quick guide to doing it. Obviously you need root privileges to install the packages. First you need to install the appropriate repository (32-bit or 64-bit) for the Adobe RPM packages: # Adobe 32-bit x86 repository rpm -ivh http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux # Adobe 64-bit x86_64 repository rpm -ivh http://linuxdownload.adobe.com/adobe-release/adobe-release-x86_64-1.0-1.noarch.rpm rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux If you cannot download these RPMs, check at Adobe for the latest version and download that. Then run yum to install the following packages: yum check-update yum install flash-plugin nspluginwrapper alsa-plugins-pulseaudio libcurl
