How to Install Particular Package Version in CentOS and Ubuntu

Posted on

Usually, when you install a package in CentOS and Ubuntu, the package management software selects the latest package version from the repository, by default. However, sometimes, for one reason or the other, you may want to install a specific package version on your Linux system.

In this article, we will explain how to install a particular or specific package version in CentOS and Ubuntu using Yum and APT front-end package managers, respectively.

Install Specific Package Version in CentOS/RHEL/Fedora

First, you need to check for all the available versions of a package, whether installed or not. Normally, yum ignores specific versions of a package and will always try to install the latest version available.

Secondly, when you try to find info about a package, yum only shows the latest version of that package in the output of info, list or search sub-commands; but using the --showduplicates switch, you can display all package versions present in the repository.

# yum --showduplicates list nginx

List All Package Versions in CentOS

From the above command output, the naming format for packages are:

package_name.architecture  version_number–build_number  repository

The build_number represents minor changes made by the package maintainer, not by the program author, such as additional documentation, changes to configuration files, or bug fixes and more.

Once you have identified the specific version of a package (for example nginx-1.10.3-1.el7.ngx), install it as follows. Note that the name format will have to change here, to the full RPM desired, package_name-version_number as shown in the following command.

# yum install nginx-1.10.3

Alternatively, if you want to use a version with certain updates, specify the build_number (package_name-version_number-build_number) as shown.

# yum install nginx-1.10.3-1.el7.ngx

Considering the above situation, a newer version of the packages is already installed on the system. Therefore, you need to remove the installed package version, if you want to install an older version from the available packages as shown.

# yum remove nginx

Once you have removed the installed package, you can then install the specific version you desire as explained above.
