What is Version Locking?
Version locking is the process of preventing specific software packages from being updated to newer versions by the system’s package manager. This ensures that certain critical applications or dependencies remain at a specified version, providing stability and compatibility within the environment.
Steps to Version Lock RPM Packages
To manage version locks using DNF or Yum, you need to install the respective version lock plugin.
For CentOS 7:
yum install yum-versionlock
For AlmaLinux, Rocky Linux, CloudLinux 8+:
dnf install python3-dnf-plugin-versionlock
Once installed, you can version lock a package using the following command:
yum versionlock <PACKAGENAME>
To view packages currently under version lock:
yum versionlock list
After resolving RPM package issues, such as through a newer update or resolving dependency conflicts, you can unlock a package with:
yum versionlock delete <PACKAGENAME>
To clear all version locks for all packages:
yum versionlock clear
Benefits of Version Locking
- Stability: Prevents automatic updates that might introduce bugs or incompatibilities.
- Compatibility: Ensures that dependent applications or libraries remain compatible.
- Control: Provides administrators with better control over the software environment.
- Predictability: Maintains consistent software versions across multiple systems, simplifying management and troubleshooting.
Conclusion
Version locking RPM packages is a powerful technique to maintain system stability, ensure compatibility, and control software updates. By following the steps mentioned above, you can easily perform version locking. Whether through manual commands or automated scripts, version locking provides a robust solution to prevent unwanted updates and maintain a predictable software environment.
