Ubuntu 18.04

The Beta release of Ubuntu 20.04 LTS is now available to download, and/or upgrade from an old Ubuntu edition.

Ubuntu 20.04 is a Long Term Support release with 5-year support. It’s scheduled to be officially released on April 23rd.

The new LTS features:

  • Linux 5.4 Kernel.
  • Gnome 3.36.
  • New dark mode setting.
  • Show computer’s vendor logo on startup.
  • WireGuard Support out of the box.
  • And WiFi (RTL8723DE) works out of the box in my HP laptop

Download / Upgrade to Ubuntu 20.04:

The 64-bit desktop and sever images are available to download at the link below:

Download Ubuntu 20.04

Though I would recommend to do a fresh install of the new LTS, you can now upgrade to Ubuntu 20.04 beta (then upgrade to final from beta) directly from Ubuntu 18.04 and or Ubuntu 19.10.

The Beta release may contain bugs. Don’t Do This on product machine before Ubuntu 20.04 goes stable!

1.) First make backup of all your important data.

2.) Disable all third-party PPAs (Software & Updates -> Other Software)

3.) open terminal (Ctrl+Alt+T) and run command to install system updates.

sudo apt update

sudo apt upgrade

You may need to restart to apply the updates.

4.) Finally run command and click “Upgrade” to get started.

sudo update-manager -d

If you’re running on Ubuntu server without an UI, run sudo do-release-upgrade -d instead.

QQ for Linux, the popular instant messaging apps developed by Tencent, released the second Beta on April Fools’ Day.

The development of QQ on Linux is quite slow. It has been 5 months since the last release. QQ for Linux 2.0 Beta 2 features:

  • Stability improvements.
  • Group chat support.

The new beta now is much more stable than the first release, though it so far only supports for sending texts, emoji, files, and taking screenshots.

If you’re looking for QQ Linux package with full (or most) functionality, I’d recommend Deepin Wine QQ, or community build QQ Flatpak package.

For testing purpose, you may download QQ for Linux (64-bit) at the link below:

QQ for Linux

Simply double-click the package to install it via Ubuntu Software and enjoy!

(Optional) To remove the IM, simply open terminal (Ctrl+Alt+T) and run command:

sudo apt remove linuxqq

upgrade Linux Kernel

Linux Kernel 5.6 was officially released. Linus Torvalds announced:

So I’ll admit to vacillating between doing this 5.6 release and doing another -rc.

This has a bit more changes than I’d like, but they are mostly from davem’s networking fixes pulls, and David feels comfy with them. And I looked over the diff, and none of it looks scary. It’s just slightly more than I’d have preferred at this stage – not doesn’t really seem worth delaying a release over.

So about half the diff from the final week is network driver fixlets, and some minor core networking fixes. Another 20% is tooling – mostly bpf and netfilter selftests (but also some perf work).

Linux Kernel 5.5 features WireGuard VPN support, and a lot of other notable improvements, including initial USB 4 support, Amazon’s Echo smart speaker, new Intel, AMD, and Arm hardware enablement.

How to Install Linux Kernel 5.6 in Ubuntu:

The mainline kernels do not include any Ubuntu-provided drivers or patches. They are not supported and are not appropriate for production use

The mainline kernel packages for Linux 5.6 are now available for download at the link below:

Download Kernel 5.6

Depends on your OS type, download and install the packages in turns:

  1. linux-headers-5.6.0-xxxxxx_all.deb
  2. linux-headers-5.6.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.6.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  4. linux-image-xxx-5.6.0-xxx-generic(/lowlatency)_xxx_amd64.deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, or armhf, arm64, etc for other OS types.

Alternatively you can download and install the kernel binaries via terminal commands ( open terminal via Ctrl+Alt+T):

For 64-bit OS:

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6/linux-headers-5.6.0-050600_5.6.0-050600.202003292333_all.deb
