Ubuntu 26.04 LTS Increases Minimum RAM to 6GB

Canonical has announced increased minimum system requirements for its upcoming Ubuntu 26.04 Long Term Support (LTS) release, codenamed "Resolute Raccoon." The desktop version of Ubuntu 26.04 LTS will now require a minimum of 6GB of RAM. The release is scheduled for April 23.

Updated System Requirements for Ubuntu 26.04 LTS

The official specifications for Ubuntu Desktop 26.04 LTS include:

  • Processor: A 2GHz dual-core processor or better.
  • RAM: Minimum 6GB.
  • Storage: 25 GB of free hard drive space.

For Ubuntu Server 26.04 LTS, resource requirements are adaptable to specific use cases, with minimums starting at 1.5 GB RAM and 4 GB of hard drive space.

Historical Context of RAM Requirements

This adjustment represents the first change in Ubuntu's desktop RAM requirements since 2019, when Ubuntu 18.04 LTS increased the minimum from 2GB to 4GB. Prior to that, Ubuntu 14.04 LTS raised the minimum RAM requirement from 384MB (for Ubuntu 12.04 LTS) to 1GB.

This marks the latest step in a trend of increasing minimum RAM requirements for Ubuntu Desktop over the past decade.

Market Conditions and Industry Trends Impacting Memory Prices

The increase in RAM requirements occurs amidst a period of rising memory component prices. This trend is influenced by factors such as demand from the artificial intelligence (AI) sector. The impact has been observed in various consumer hardware, including specific models like the Raspberry Pi 5 16GB, which have experienced price increases since November. Reports indicate that these price trends are extending to other memory types, including non-volatile solid-state storage, with no immediate improvement in component shortages expected.

Rising memory component prices, driven significantly by AI demand, are affecting various hardware sectors with no immediate relief in sight.

Comparative System Requirements

When compared to other major operating systems:

  • Ubuntu 26.04 LTS: Requires 6GB RAM and 25GB of storage.
  • Microsoft Windows 11: Specifies a 1GHz, two-or-more core 64-bit processor, at least 4GB of RAM, and 64GB of storage.
  • Apple macOS 11 "Big Sur": Requires 8GB of RAM.

Alternatives for Systems with Lower RAM

For users with systems containing 4GB of RAM, an alternative exists: installing Ubuntu 26.04 Server LTS and subsequently adding a lightweight desktop environment. This approach can reduce the necessary RAM to as little as 1.5GB for the base system.

Users with 4GB of RAM can install Ubuntu 26.04 Server LTS and add a lightweight desktop environment as an alternative.
However, operating modern web browsers with multiple tabs typically necessitates 8GB of RAM or more for optimal performance. For optimal performance, especially when using modern web browsers, 8GB of RAM or more is generally recommended.
