What is LTS & ESM?

LTS (Long-term support) release comes with 5 years of technical support, security patches and critical fixes for Ubuntu since its 6.06(Dapper Drake) LTS release.

ESM (Extended Security Maintenance): When Ubuntu LTS user’s reaches their 5-year’s term, ESM provides access to critical and important security patches beyond the five-year support time frame.
