‘ca-certificates’ update error

Since the last “ca-certificates” release for RHEL/CentOS 6 or Fedorar 14 with version stating 2013, there is a roaming error of not being able to update “ca-certificate” version starting from 2010 to the latest 2013. The error is somewhat looks the following through yum:

Running Transaction

Failed:
ca-certificates.noarch 0:2010.63-3.el6_1.5 ca-certificates.noarch 0:2013.1.94-65.0.el6

The following part of the error to be noted:

error: unpacking of archive failed on file /etc/ssl/certs: cpio: rename

It looks like the new “ca-certificate” is using a new structure. In old versions, “certs” is a folder which contains old certificates. While updating with the new one, it is trying to create a symlink with the /etc/pki/tls/certs/ by removing the old directory, which it fails with yum.

To solve the error, run the following:

$ mv /etc/ssl/certs /etc/ssl/certs.back
$ ln -s /etc/pki/tls/certs /etc/ssl/certs
$ yum update ca-certificate*

This should solve the error.

There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them

While updating CentOS/RHEL system using Yum, the following error appears:

There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them

How do I fix this in CentOS/RHEL 5.x/6.x system?

You have some broken or aborted yum transactions in the system. It was possibly due to yum was forcefully interrupted in the middle of a transaction. To fix this, run the following:

$ yum-complete-transaction

The command can return the following:

$ yum-complete-transaction
bash: yum-complete-transaction: command not found

It means you do not have yum-utils package installed in your system. Run the following to install yum-utils

$ yum install yum-utils

This will install necessary for yum-complete-transaction.

Install rtorrent in RHEL/CentOS

The easiest way to install rtorrent (a command line bittorrent client) is to use the RPMForge Repository. You can install RPMForge using the following artcle How to install RPMForge Repository in RHEL/Centos.

Once you are done, you just need to run the following command to install rtorrent in your RHEL/CentOS (5/6):

yum install libtorrent rtorrent libsigc

libsigc++ is a dependency library for libtorrent. Yum should include it automatically in the installation. RPMForge has the compatible libsigc++ in their repository.

rtorrent: symbol lookup error: rtorrent: undefined symbol

How to fix the error “rtorrent: symbol lookup error: rtorrent: undefined symbol”?

If you have installed rtorrent using RPMForge Repository, you are possibly seeing the error with libtorrent “0.13.2-1”. There is a conflict between the latest libtorrent and rtorrent. The easiest way, I have found to solve the error is to downgrade the libtorrent version using the same repository. Run the following to downgrade the libtorrent:

yum downgrade libtorrent

This should downgrade your libtorrent version to 0.12.9-2, which seems to work fine with rtorrent 0.8.9-2.
