How to Upgrade Ubuntu 18.04 to Ubuntu 20.04 Beta

Last updated: April 4, 2020

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.

      A very good tutorial. Most tutorials I have read leave out removing the third party PPA’s, and I can see where that could cause a problem. Personally I prefer a clean install. Therefore I await the final release of Ubuntu Mate.

      I like that Ubuntu 20.04 comes with the rtl8723de driver out of the box. I believe that it is the first distribution to do so. Is the wifi working well without adding the ant_sel option? I followed your tutorial on this website on how to install the driver and it works best on my HP laptop with ant_sel=2.

        WiFi is working well in my case without any change.

          Can the Realtek WiFi rtl8723de be installed via the Additional Drivers section in the Software and Updates app? Can the driver information also be viewed in the Additional drivers’ section?

            Recently installed Ubuntu 20.04 and the rlt8723de driver works superb as Intel’s WiFi driver. No configuration is necessary unlike before where I had to set ant_sel=2 for best performance of the driver.
