A review of Ubuntu 20.04 LTS
The Ubuntu 19.10 life cycle will come to an end in July, and after that the biggest release for some time will be Ubuntu 20.04 LTS, with major updates and improvements ending by 2030.
20.04 is the 8th LTS release of Ubuntu and is scheduled for release on April 23 next year. Canonical has a 25-week schedule for 10 monthly releases and a 27-week schedule for April releases to guide LTS development, and Ubuntu 20.04’s development lifecycle follows the 27-week schedule.

From this table we can see several key nodes:
- Feb. 27: Features freeze
The Ubuntu team stopped introducing new features, packages, and apis, and they began to focus on fixing bugs in the development build.
- March 19: Freezes the user interface
At this point, no other updates will occur in the user interface. Later, document processing will also begin, including the latest screen shots.
- March 26: Freeze docstrings
After all feature and user interface updates are complete, the document stops creating and modifying strings. If you need to change the string at a later stage, you can only add it with the team’s approval.
- April 2: Beta freeze
Developers experience Ubuntu beta versions and suggest bugs or bug fixes before the official release.
- April 9: The kernel freezes
The kernel freeze is the deadline for kernel updates.
- April 16: Final freeze
The final freeze is the penultimate phase of the final release, when the team confirms all fixes.
- April 23: Final stable release
The final stable version is officially available.
New features of Ubuntu 20.04
The first is theme change. Yaru has an optional theme change from light to dark, and the check boxes, radio buttons, sliders and progress bars under this theme are no longer blue or green, but purple instead. Switching from green to purple reduces the color clutter overall, without destroying the harmony of Ubuntu itself.
Second, another long-awaited demand of the Ubuntu community will be met by removing pre-installed Amazon apps from the system. The Amazon icon on Ubuntu has long been on the desktop and has long been mocked for being too weak, and this is reflected in the data. This change, especially for the Chinese, who are generally not used to Amazon as the first choice for shopping, is a good thing.
Ubuntu 20.04 will use the Linux 5.4 kernel, which has new features such as kernel lock mode and exFAT support.
Kernel locking is designed to prevent the root account from tampering with the kernel code, thereby separating the user-mode process from the code. After this function is enabled, even the root account cannot access certain kernel functions, thus protecting the operating system from the impact of the damaged root account.
ExFAT file system is FAT32’s replacement. It was developed by Microsoft, but not only for Windows, exFAT has been widely used in the entire electronics industry, especially in SD cards, USB flash drives, digital cameras and MP3 players. Most of the time you use these electronic products, you are using exFAT technology.
On the other hand, support for ZFS as a root directory introduced in 19.10 will be further improved, but it will remain experimental.
The ZFS debate was recently heated up by Linus Torvalds, who mentioned ZFS on a forum discussing kernel issues. He doesn’t recommend ZFS until Oracle relicenses the ZFS code to make it more user-friendly for the Linux kernel mainline, and even beyond the license, Linus doesn’t think the overall performance of ZFS is particularly strong. It was then publicly declared that Linus did not understand ZFS.
In addition, other 20.04 enhancements include:
- GNOME was upgraded from V3.34 to V3.36
- Game-related improvements
