FAQs

The recommended minimum hardware requirements below should allow users to easily install a usable Ubuntu system with enough room to be comfortable:

1. 2 GHz dual core processor 
2. 4 GiB RAM (system memory)
3. 25 GB (8.6 GB for minimal) of hard-drive space (or USB stick, memory card or external drive but see LiveCD for an alternative approach) 
4. VGA capable of 1024x768 screen resolution 
5. Either a CD/DVD drive or a USB port for the installer media 
6. Internet access is helpful 

It’s worth noting that even PCs with lower specifications than these can see performance improvements and their lifetime extended with Ubuntu, even if they have lower specifications than the ones described above.

Ubuntu releases get a development codename (‘Mantic Minotaur’) and are versioned by the year and month of delivery - for example, Ubuntu 23.10 was released in October 2023.

LTS or ‘Long Term Support’ releases are published every two years in April. An estimated 95% of all Ubuntu installations are LTS releases.

Ubuntu LTS releases receive 5 years of standard security maintenance for all packages in the ‘Main’ repository. With an Ubuntu Pro subscription, you get access to Expanded Security Maintenance (ESM) covering security fixes for packages in both the ‘Main’ and ‘Universe’ repositories for 10 years. Phone and ticket support is also available and can be optionally added on top of an Ubuntu Pro subscription, covering the same packages covered by ESM, for the same time frame.

An optional Legacy support add-on on top of Ubuntu Pro extends security maintenance and support for an additional 2 years, resulting in 12 years coverage overall.

Every six months between LTS versions, Canonical publishes an interim release of Ubuntu, with 23.10 being the latest example. These are production-quality releases and are supported for 9 months, with sufficient time provided for users to update, but these releases do not receive the long-term commitment of LTS releases.
