The June 2026 Secure Boot Certificate Expiry: What You Need to Know

on
If you dual-boot or run a Linux distribution with Secure Boot enabled, you may have heard about a major security deadline. The original Microsoft 2011 UEFI Third-Party Certificate Authority (CA) keys, which most Linux distributions rely on to sign their initial bootloaders (shim) on consumer PC hardware, expired at the end of June 2026 The expiration of a certificate doesn't invalidate already-installed, signed binaries on your system; firmware doesn't check expiration dates at boot time. However, moving forward, future Linux bootloader updates and security patches will be signed exclusively using the new Windows UEFI CA 2023 key . If your motherboard's firmware database isn't updated to trust this new 2023 key, your Linux system may eventually experience package management blocks or fail to apply critical bootloader updates. Before running updates, check if Secure Boot is active and see if your system already recognizes the 2023 certificate hierarchy. Open your termi...

Stock vs. Custom ROM Solutions

on

As a tech enthusiast who spends a significant amount of time exploring the capabilities of various devices, I recently encountered a persistent issue with my Pixel 8 Pro. While generally a powerful and impressive device, it seems to struggle particularly when updating apps or browsing the Google Play Store. This lag can be frustrating, making the experience feel sluggish and detracting from the otherwise smooth operation of the phone.

Lag while using the Google Play Store on the Pixel 8 Pro is not an isolated issue. Many users report similar problems, where the system becomes unresponsive or slow, especially during app updates. This can be attributed to several factors:

Occasionally, software bugs can cause the system to slow down, especially during resource-intensive tasks like app updates. Numerous background processes can compete for system resources, leading to reduced performance.

Over time, cache files can accumulate, causing the Play Store to lag. Clearing the cache might help, but it’s often a temporary fix. Some apps might be resource-intensive, causing the system to slow down when they’re running or updating.

After exhausting these options, I decided to explore installing a custom ROM, specifically LineageOS. Custom ROMs are known for their ability to optimize performance and offer more control over system settings. Here’s what I found:

LineageOS is optimized for performance, often resulting in a smoother, more responsive experience. This was immediately noticeable, with significantly less lag when using the Play Store and updating apps and offers a wealth of customization options, allowing users to tweak the system to their liking, potentially enhancing both usability and performance.

Unlike stock firmware, LineageOS comes with minimal pre-installed apps, freeing up system resources and reducing potential sources of lag.
The active LineageOS community ensures regular updates, which can include performance improvements and new features.


For those who are comfortable with the process, installing a custom ROM can be a rewarding way to enhance the performance and extend the life of your device. As always, back up your data and proceed with caution, but don't be afraid to experiment and find the solution that works best for you.
