Linux Kernel 6.19 Reaches End of Life: Time to Move Forward

1 week 2 days ago
by George Whittaker

The Linux kernel continues its fast-paced release cycle, and with that comes an important milestone: Linux kernel 6.19 has officially reached end of life (EOL). For users and distributions still running this branch, it’s now time to upgrade to a newer kernel version.

This isn’t unexpected, Linux 6.19 was never intended to be a long-term release, but it does serve as a reminder of how quickly non-LTS kernel branches move through their lifecycle.

Official End of Support

The final update in the 6.19 series, Linux 6.19.14, has been released and marked as the last maintenance version. Kernel maintainer Greg Kroah-Hartman confirmed that no further updates will follow, stating that the branch is now officially end-of-life.

On kernel.org, the 6.19 series is now listed as EOL, meaning it will no longer receive bug fixes or security patches.

Why 6.19 Had a Short Lifespan

Unlike some kernel releases, Linux 6.19 was not a long-term support (LTS) version. Short-lived kernel branches are typically supported for only a few months before being replaced by newer releases.

Linux follows a rapid development model:

  • New major versions are released frequently
  • Short-term branches receive limited updates
  • Only selected kernels are designated as LTS for extended support

Because of this, 6.19 was always meant to be a stepping stone rather than a long-term foundation.

What Users Should Do Now

With 6.19 no longer maintained, continuing to use it poses risks, especially in environments where security and stability matter.

Recommended upgrade paths include:

Upgrade to Linux 7.0

The most direct path forward is the Linux 7.0 kernel series, which succeeds 6.19 and introduces new hardware support and ongoing fixes.

This is a good option for:

  • Desktop users
  • Rolling-release distributions
  • Users who want the latest features
Switch to an LTS Kernel

For production systems, servers, or long-term stability, moving to an LTS kernel is often the better choice.

Current LTS options include:

  • Linux 6.18 LTS (supported until 2028)
  • Linux 6.12 LTS (supported until 2028)
  • Linux 6.6 LTS (supported until 2027)

These versions receive ongoing security updates and are better suited for stable environments.

Global Growth In Solar 'the Largest Ever Observed For Any Source'

1 week 2 days ago
The IEA says 2025 marked a turning point for global energy, with solar posting the largest growth ever seen for any energy source and helping carbon-free power outpace rising demand. The trend led the agency to declare that the world has entered the "Age of Electricity." Ars Technica reports: The IEA report covers energy use, including the electrical grid, transportation, home heating, and other forms of consumption. As such, it can track how some of those uses are shifting, as electric vehicles displace some gasoline use and heat pumps replace gas and oil heating. It also saw a more global trend: The demand for electricity grew at twice the rate of overall energy demand. All of these went into the conclusion that we're starting the Age of Electricity. In terms of specifics, the IEA saw electric vehicle demand rise by nearly 40 percent, with electric car sales being a quarter of the total of cars sold last year. While that's having a measurable effect on electricity demand, it remains relatively small at the moment. It's almost certain to be contributing to the size of the rise in oil use last year: 0.7 percent. In absolute terms, that's less than half the average rise of the previous decade. [...] When it comes to supplying electrons for those alternatives, the central story is solar power. "The absolute increase of solar PV generation in 2025 is the largest ever observed for any source," the IEA says, "excluding years marked by rebounds from global economic shocks such as COVID-19." In other words, with nothing in particular driving the energy markets in 2025, Solar's growth was unprecedented. On its own, its growth covered a quarter of the rising demand for all forms of energy. If you limit it to electricity, increased solar production covered over two-thirds of the increased demand. Overall, solar generated over 2,700 terawatt-hours last year, more than double its output from three years earlier. It now accounts for over 8 percent of the world's total electricity production. Thirty individual countries installed at least a gigawatt of solar last year, and it is now the single largest grid source by capacity (though other sources still outproduce it at the moment).
