Powerful package management tools like the Yellowdog Updater, Modified (YUM) are frequently found in Linux distributions like CentOS and Fedora. The procedure for installing, updating, and deleting software items from your system is made simpler. As it helps to free up disk space and keep your system lean and effective, uninstalling unused software is an essential part of system maintenance. This article will offer a thorough, step-by-step tutorial on uninstalling YUM packages, providing a simple and trouble-free procedure.
Understanding YUM Package Management
Let’s quickly define YUM and its function in package management before moving on to the uninstalling procedure. The installation, erasure, and updating of software packages are all automated by the package management YUM. It resolves inter-package dependencies, ensuring that all necessary components are correctly installed.
One of YUM’s key benefits is its user-friendly interface, which makes it simple for both new and seasoned Linux users to manage packages effectively.
Identifying Targeted Packages for Uninstallation
Finding the YUM packages you wish to remove is the first step in the removal process. Use the following command in your terminal to accomplish this:
| $ yum list installed |
This will show a list of every package that is currently installed on your system. Review the list and mark the packages you want to uninstall. Avoid uninstalling essential system components because doing so could cause stability and functionality problems.
Uninstalling YUM Packages
It’s time to start the uninstallation procedure when you’ve determined which packages to remove. Consider looking for package dependencies that could be impacted by the removal before moving forward. Running will enable you to:
| $ yum deplist package_name |
where package_name denotes the package you want to uninstall.
Make a backup of your system or take a system snapshot if you want to be safe so you can restore it if there are any problems with the removal.
Use the following command to remove a single package:
| $ sudo yum remove package_name |
Replace package_name with the name of the package you want to uninstall.
For removing multiple packages simultaneously, use the following command:
| $ sudo yum remove package_name1 package_name2 package_name3 |
YUM will automatically resolve dependencies and remove the chosen packages as soon as you confirm the removal.
Purging Unused Dependencies
There may be unnecessary dependencies left over after uninstalling packages. You can get rid of these orphaned dependencies to clear up your system and free up disk space by executing:
| $ sudo yum autoremove |
Unused dependencies will be automatically found and removed using this command.
Reverting Package Installation (Downgrading)
You might occasionally need to return to an earlier version of a package. You can go back in time by installing a package using YUM’s history feature. Run: to examine the YUM history.
| $ yum history |
Then, use the command below to downgrade: Find the transaction ID connected to the package installation.
| $ sudo yum history undo transaction_id |
Replace transaction_id with the actual ID number.
Troubleshooting Common Uninstallation Problems
Occasionally, while performing the removal, you could run into conflicts or dependence problems. Try the following to fix these issues:
Forced Removal: To force the removal while skipping any outstanding dependencies, use yum remove –skip-broken package_name.
Reinstalling the Package: Before removing a package that isn’t working properly, consider reinstalling it first.
Conflicting Packages Removal: Before uninstalling your target package, manually remove any incompatible packages.
Restoring from backup:If everything else fails, you may always restore your system from a backup you made before removing an application.
Best Practices for YUM Package Management
Follow these best strategies to maintain a strong, effective system:
Continual Updates: Run sudo yum update frequently to keep your system up to date.
Using Trusted Repositories: To prevent installing potentially hazardous or unstable packages, only use trustworthy YUM repositories.
Avoid Manual Package Removal: To ensure correct handling of dependencies, utilize whenYUM for package managementever possible.
Conclusion
Although uninstalling YUM packages is a simple procedure, dependencies and potential conflicts must be carefully taken into account. This step-by-step manual will help you eliminate pointless programs and keep your Linux system tidy and optimal. Always be cautious when deleting packages, and for extra security, think about creating backups or taking system snapshots.
