How to use yum to list All versions of Package in Linux
The default behavior of yum is to install the most recent version of a package from the enabled repositories. However, there are situations where it may be necessary to install a particular version or revert to an earlier version of a package that is already installed.
In this post, we will show how to make yum list all available versions of a specified package and how to instruct it to install the particular one.
Show All Versions of Package with yum
Run the following command to show all versions of a package, available in enabled repositories:
# yum list glibc-locale-source —showduplicates
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Last metadata expiration check: 0:31:11 ago on Wed 20 Jul 2022 02:01:41 AM GMT.
Installed Packages
glibc-locale-source.x86_64 2.28-151.el8 @wd_rpm
Available Packages
glibc-locale-source.x86_64 2.28-151.el8 wd_rpm
glibc-locale-source.x86_64 2.28-164.el8_5.3 wd_rpm
From the output, we can see that there are 3 packages in total. One package is installed. Two packages are available to install from remote repository.
Installed Packages: This section lists the packages that are currently installed on the system. In this case, it shows that the glibc-locale-source package with version 2.28-151.el8 is installed (@wd_rpm indicates it was installed from wd_rpm package repository).
Available Packages: This section lists the available packages that can be installed from the configured repositories. Here, it shows that there are two available versions of glibc-locale-source: version 2.28-151.el8 and version 2.28-164.el8_5.3. The wd_rpm tag indicates that these versions are available from remote package repository.
Install Specific Version Of Package with yum in Linux
To install a specific version of a package, run: $ sudo yum install –
yum install glibc-locale-source-2.28-151.el8
If you’re looking how install a package on Linux, we strongly suggest reading this article.
Force Yum To Downgrade Package
If we already have the latest version of a package installed, but we need to downgrade it to the particular version that is older, execute:
understanding RPM file name
RPM package files names consist of four elements (plus the .rpm suffix): name-version- release.architecture:
Here is one example. kernel-4.18.0-425.3.1.el8.x86_64
Name : kernel
Version : 4.18.0
Release : 425.3.1.el8
Architecture : x86_64
Size : 8.8 M
Only the package name is required for installing packages from repositories. If multiple versions exist, the package with the higher version number is installed. If multiple releases of a single version exist, the package with the higher release number is installed.
