TUXEDO OS Leaves Ubuntu Behind for a Debian Testing Base

TUXEDO Computers has announced a major change for its in-house Linux distribution, TUXEDO OS, revealing that Ubuntu will no longer serve as its foundation. Instead, future versions of the distro will be based on Debian Testing.

According to the company, the decision arrives after several months of reduced update cadence, especially around KDE Plasma updates. While Plasma 6.7.x is already available upstream, TUXEDO OS is still based on Plasma 6.5.x, and the company had not previously given a precise timeline for moving existing users to an Ubuntu 26.04 LTS base.

Now we know the main reason behind this: TUXEDO OS is leaving Ubuntu behind. Until now, TUXEDO OS has followed a hybrid release model which combined a stable Ubuntu LTS base with more frequently updated components such as the Linux kernel, web browsers, NVIDIA drivers, the graphics stack, and KDE Plasma.

However, TUXEDO says this model has become increasingly difficult to maintain as Ubuntu LTS releases age. According to the company, backporting modern software to an older package base requires more work over time, especially when newer applications depend on libraries that are either missing or outdated in the underlying distribution.

Additionally, the company also points to deeper technical problems. Updating central components such as Qt, which KDE Plasma heavily depends on, can break software from Ubuntu’s repositories.

But the technical maintenance is only part of the story. TUXEDO also cites Canonical’s strategic direction as one of the reasons for the move. In particular, the company says it has become harder to keep Snap out of the operating system, as Canonical continues to move more applications toward Snap packages while traditional DEB packages become less central.

TUXEDO also mentions Canonical’s AI roadmap, announced by Mark Shuttleworth during the Ubuntu Summit 26.04, saying that its concrete implementation is still not transparent…
