The ATrpms repository provides many bleeding edge software packages so if you have a development server where you install new apps this repo can be very useful. The instructions are not 100% clear about how to install this repository on CentOS Linux which would also be the same on RedHat Linux but not on Fedora Linux. Anyhow the example used on the ATrpms site relates to Fedora so the repo file needs to be modified to work on CentOS as noted below.

During an attempt to update Git on a CentOS Linux server via the Yum Package manager this evening I ran into a dependency error. The newer Git package has a dependency of Git-CVS package which also has a dependency of CVSPS package.  So initially when I installed Git it didn’t require these packages so I never ran into an error. Below I show the error displayed when attempting to upgrade git via yum followed by how I resolved the issue installing the EPEL repository.

One of the annoying things about CentOS Linux is the current dependency on Python version 2.4. Typically I install Python version 2.6 and compile new programs using the 2.6 version of python instead of the 2.4 version. Recently on a server I had just installed CentOS 5.4 on I had a dependency issue when attempting to install python version 2.6 from the CHL repository. Below I display the error and describe how to install the libffi package on CentOS Linux.

When working to create a GPG key to sign some RPM packages I was building I ran into a message I had never seen before. I was building the RPM packages on an older server with not a lot of power which I am assuming contributed to my issue. The error is noted below but basically means you need to generate a lot of random bytes which are used to create a unique key. Within the error it states that the computer needs to collect more entropy so below I explain the error in more detail, what entropy means, why more entropy is needed, and how to generate as much as possible in a short amount of time to finish generating the GPG key.

I have been working on setting up some automated tasks at work that use curl to connect to FTPS on a remote server. On one of the development servers I was testing from I attempted to issue a curl command using the “–libcurl” switch which returned an error. This command was recommended by a coworker as a start to set up the automated tasks to connect to FTPS on the remote server using curl. Below I describe the error in detail, the cause of the error, and how to resolve the error.
