Ubuntu 26.04 LTS Quietly Raises
Minimum RAM to 6GB
Canonical’s upcoming “Resolute Raccoon” release marks the first increase in desktop memory requirements since 2019 — a move experts are calling an “honesty bump” that better reflects real-world modern computing.
Canonical has quietly updated the official release notes for Ubuntu 26.04 LTS, raising the minimum RAM requirement for the flagship desktop distribution from 4 GB to 6 GB — the first such increase since 2019. The new specification, confirmed directly in the Ubuntu 26.04 release notes, lists a 2 GHz dual-core processor, 6 GB of RAM, and 25 GB of free hard drive space as the minimum to run Ubuntu Desktop.
The change, first spotted and reported by OMG Ubuntu, has drawn widespread attention from the Linux community as the upcoming long-term support (LTS) release — codenamed “Resolute Raccoon” — approaches its scheduled April 23, 2026 launch. CPU and storage requirements remain unchanged from previous releases.
The recommendation is not because Ubuntu requires 2 GB more memory than it did, but more the way we compute does — the Resolute Raccoon’s memory requirements better reflect real-world multitasking.

To understand the significance of this change, it is worth reviewing how Ubuntu’s minimum desktop RAM requirements have evolved over the years. Ubuntu 12.04 LTS “Precise Pangolin,” released in 2012, required just 384 MB of RAM for 32-bit systems, and the minimum stepped up to 1 GB with Ubuntu 14.04 LTS “Trusty Tahr” in 2014. Ubuntu 18.04 LTS “Bionic Beaver” launched in 2018 initially with a 2 GB minimum, but following community feedback, Canonical updated the requirement to 4 GB in 2019 — which is why this new increase is described as “the first since 2019” rather than since 2018.

| 12.04 LTS Precise Pangolin |
2012 | 384 MB (32-bit) 512 MB (64-bit) |
1 GHz | 5 GB |
| 14.04 LTS Trusty Tahr |
2014 | 1 GB | 1 GHz | 5 GB |

2024 | 4 GB | 2 GHz dual-core | 25 GB |
| 26.04 LTS Resolute Raccoon |
2026 | 6 GB New | 2 GHz dual-core | 25 GB |
* Ubuntu 18.04 LTS originally launched in 2018 with a 2 GB minimum. The requirement was updated to 4 GB in 2019 following community feedback. Requirements were unchanged for Ubuntu 16.04 LTS, 20.04 LTS, and 22.04 LTS.
Why Now? An “Honesty Bump,” Not a Heavier OS
Canonical and independent Linux analysts are framing the change not as a sign that Ubuntu itself has ballooned in resource consumption, but rather as a more candid acknowledgment of how people actually use their computers today. With GNOME 50 as the new default desktop environment, updated versions of Firefox, LibreOffice, Thunderbird, and GIMP all shipping with the release, and modern multitasking workflows involving browser tabs, flatpak containers, live search indexing, and crash-dump tooling all running in the background, 4 GB has increasingly become an uncomfortable floor rather than a comfortable baseline.

Not a Hard Requirement — But Expect Sluggishness
Despite the updated specification, 6 GB is not enforced as a hard installation barrier. Ubuntu 26.04 will still install on machines with less RAM — but Canonical is making clear that users should not expect smooth performance below the listed minimum. OMG Ubuntu independently tested the Ubuntu 26.04 Beta on a laptop equipped with just 2 GB of RAM and confirmed the OS was technically functional, though it described the experience as slow to the point of frustration.
The storage requirement of 25 GB remains the only truly hard constraint — Ubuntu Desktop’s installer will refuse to proceed on any device with less than 25 GB of available disk space, a rule that has been in place since Ubuntu 18.04 LTS.
Server Users: No Change
The updated requirements apply exclusively to the desktop edition. Ubuntu Server 26.04 LTS remains far more flexible, with Canonical’s documentation retaining a minimum of 1.5 GB of RAM for ISO-based installations and suggesting at least 3 GB for practical production workloads. Server edition images also continue to be available as pre-built images for cloud, virtualized, and bare-metal environments.
Alternatives for Lower-Memory Machines
For users whose hardware falls short of 6 GB, Canonical and the wider Ubuntu community offer several paths that extend the life of older machines without sacrificing the Ubuntu ecosystem entirely.
Official Ubuntu flavour built on the LXQt desktop. Significantly lighter than GNOME while sharing Ubuntu’s base system and package repositories.
Ubuntu flavour using the Xfce desktop environment. A solid balance between usability and resource efficiency for machines in the 2–4 GB range.
Use the Ubuntu netboot installer to deploy a minimal base system, then manually layer on only the desktop components you need — for experienced users.
Install Ubuntu Server (1.5 GB minimum) and add a lightweight desktop environment such as i3, bspwm, or LXQt on top for a highly tuned system.
Context: Memory Prices and the Broader Climate
The announcement arrives at an awkward moment for budget users. Ongoing RAM shortages tied to global supply constraints and the surging demand driven by AI infrastructure have already pushed memory module prices higher across consumer and enterprise markets in 2025 and early 2026. Critics note that a 50% increase in the stated minimum RAM — from 4 GB to 6 GB — carries more real-world cost implications than in previous years when memory was more affordable and plentiful.
Canonical’s response, as reflected in the framing from the wider Linux press, is that the 6 GB figure is an honest representation of what users need to have a satisfactory experience — rather than a marketing number calibrated to the cheapest hardware still technically capable of booting the OS. Whether this framing satisfies users who own 4 GB machines remains to be seen, but Ubuntu 26.04 LTS does stop well short of mandating new hardware.
Ubuntu 26.04 LTS “Resolute Raccoon” is currently in development and scheduled for release on April 23, 2026. It will receive standard security updates for five years through April 2031, with an additional five years of Expanded Security Maintenance (ESM) available to Ubuntu Pro subscribers.
