Release Cadence
Releases of Ubuntu get a development codename (“Breezy Badger”) and are versioned by the year and month of delivery - for example Ubuntu 17.10 was released in October 2017. LTS or “Long Term Support” releases are published every two years in April. Every six months between LTS versions, Canonical publishes an interim release of Ubuntu. See this link for more details on the Ubuntu Release Cycle.
Support Lifecycle
LTS releases are in “General Support” for 5 years and “Extended Security Maintenance” (see below)
for an additional 5 years. Ubuntu breaks General Support into “Hardware and Maintenance updates”
(2 years) followed by “Maintenance Updates” for another 3 years1. Interim releases (non-LTS) are
supported for 9 months. Packages in main and restricted are supported for 5 years in long term
support (LTS) releases. Ubuntu Flavors generally support
their packages for 3 years in LTS releases but there are exceptions.
During the lifetime of an Ubuntu release, Canonical provides security maintenance. Basic Security
Maintenance covers binary packages that reside in the main and restricted components of the
Ubuntu archive, typically for a period of 5 years from LTS release.
Packages in universe are expected to be community-supported on a best-effort basis during the LTS
phase, but in practice, security-updates are only released to pro subscriptions.
Extended Security Maintenance (ESM) provides security updates on Ubuntu LTS releases for additional 5 years. It is available with the Ubuntu Pro subscription or a Free subscription for personal use2.
Ubuntu Pro offers security fixes for critical, high, and selected medium CVEs in the main and
universe repositories. Ubuntu Pro (Infra-only)3 only guarantees security fixes for packages in
the main repository.
Support Comparison
| Feature/Plan | Ubuntu LTS | Ubuntu Pro (Infra-Only) 3 | Ubuntu Pro |
|---|---|---|---|
| Main repository | 5 years | 10 years | 10 years |
| Restricted repository | 5 years | 10 years4 | 10 years 4 |
| Universe repository | Best Effort5 | Best Effort | 10 years |
| Phone/Ticket Support | No | Yes | Yes |
| Kernel Live Patching | No | Yes | Yes |
| Security Certifications and Hardening6 | No | Yes | Yes |
| Ubuntu Landscape | No | Yes | Yes |
For package specific support details, the following commands are available:
-
ubuntu-security-statuscommand (ubuntu-support-statuson versions before20.04) for non-ESM. -
pro security-statusfor ESM.
-
The difference between these 2 is unclear, and not explained. ↩
-
Anyone can use Ubuntu Pro for free on up to 5 machines, or 50 if you are an official Ubuntu Community member. ↩
-
The restricted repository isn’t explicitly listed in the Ubuntu Pro list of supported repositories, but it is likely supported. ↩ ↩2
-
While promised, Canonical doesn’t seem to be backporting any security-fixes in the universe repository to users without a Pro subscription. ↩
-
This includes NIST-certified FIPS crypto-modules, USG hardening with CIS and DISA-STIG profiles, and Common Criteria EAL2. ↩
