LTS Releases and Upgrades

LTS (Long Term Support) releases are versions of software that receive extended support and maintenance for a predetermined period. In the context of Linux distributions, LTS versions are typically stable releases that are maintained for several years, ensuring security updates and critical bug fixes without introducing breaking changes.

LTS releases are designed for users who prioritize stability and reliability over having the latest features. Examples include:

• Ubuntu LTS (e.g., Ubuntu 22.04 LTS)
• Debian Stable (e.g., Debian 11)
• CentOS (e.g., CentOS 8)

These releases typically receive updates for:

1. Security patches
2. Critical bug fixes
3. Hardware enablement stacks

Upgrading from one LTS release to another can be a straightforward process if planned properly. Here's a step-by-step guide for upgrading Ubuntu LTS:
