Ubuntu has long been known as the go-to Linux distribution for people who want an open-source desktop that runs well on modest hardware. That reputation is now being tested, because Ubuntu 26.04 LTS is arriving with noticeably higher minimum PC requirements than many users expect.
Ubuntu 26.04 LTS, which is expected to roll out later this month, lists a 2 GHz dual-core processor, at least 6 GB of RAM, and 25 GB of free storage as the recommended baseline for a standard desktop installation. For anyone used to installing Ubuntu on older laptops or budget machines, the memory requirement in particular stands out.
What makes the change more surprising is how it compares to Windows 11 on paper. Microsoft’s official Windows 11 requirements include a 1 GHz or faster dual-core processor and a minimum of 4 GB of RAM, alongside 64 GB of storage. In raw CPU clock speed and minimum memory, Ubuntu 26.04 LTS appears more demanding, with double the CPU clock figure and 50% more RAM listed than Windows 11’s minimums.
That said, the real-world experience of getting the operating system onto a PC is where Ubuntu still holds a major advantage. Ubuntu’s requirements are not enforced in the same strict way. Users can still install Ubuntu Desktop on lower-spec systems, including machines with as little as 2 GB of memory, and Ubuntu Server can run with even less, starting around 1.5 GB of RAM. In other words, the published requirements may represent a more comfortable target for modern desktop usage, but Ubuntu remains flexible for people trying to keep older hardware useful.
Windows 11, on the other hand, comes with additional platform checks that go beyond CPU, RAM, and storage. Microsoft requires features such as Secure Boot and TPM 2.0, and those requirements can prevent installation on many otherwise capable PCs unless users rely on workarounds. There are also newer hardware expectations tied to Microsoft’s Copilot+ push, such as systems designed around AI PC capabilities, including NPUs rated at 40+ TOPS. While those AI-focused requirements are aimed at a specific category of devices rather than the core Windows 11 experience, they add to the overall perception that Windows has more hard barriers for everyday users.
The bottom line is that Ubuntu 26.04 LTS is signaling a shift toward more modern baseline hardware for the desktop experience, which could make it less attractive for some entry-level and older PCs if users stick strictly to the recommendations. However, Ubuntu’s install-anyway flexibility still makes it more approachable for people who want control, fewer roadblocks, and the option to run Linux on hardware that doesn’t meet a strict checklist.
