Download and Install openEuler on Raspberry Pi

This video show how to download, install and run openEuler on Raspberry Pi, and switch language to English. Tested on Raspberry Pi 4B/4G with 7 inch mini HDMI LCD. Chinese is set system language by default, this video also show how to switch to English.

Download openEuler image for Raspberry Pi
(prepare on Raspberry Pi)

Visit https://www.openeuler.org/en/, scroll down and click on "use openEuler OS", choose Raspberry Pi.

In the new opened page, scroll down to How to download latest image, (https://gitee.com/openeuler/raspberrypi#how-to-download-latest-image).

Select the image to download, in my test: openEuler 20.03 LTS SP1 alpha4 (DDE desktop and Chinese input method),  openEuler-20.03-LTS-SP1-DDE-raspi-aarch64-alpha4.img.xz.

Extract the downloaded file. Then we can write the extracted image on microSD using Raspberry Pi Imager.

Then you can boot-up Raspberry Pi with the microSD. 

User and password:

The image pre-set with System user/password:
- root/openeuler 
- pi/raspberry

DDE cannot log in with root account, you can login user pi using password "raspberry".


FYI: the microSD I used in this test is 128G Samsung Evo Plus:

Install openEuler in VirtualBox, and install Deepin Desktop Environment (DDE)

openEuler is an innovative platform nurtured by community collaboration. It aims to build a unified and open OS that supports multiple processor architectures, and to advance the hardware/software application ecosystem.

This video show how to install openEuler in VirtualBox 6.1/Windows 10.


Visit https://www.openeuler.org/en/download/ to download ISO. It's openEuler-20.03-LTS-SP2-x86_64-dvd.iso in my case.

It's very straightforward to install openEuler in VirtualBox. But there are no desktop environment by default. Deepin Desktop Environment (DDE) can be installed using dnf (a Linux software package management tool).

Most probably you cannot run dnf, fail with error [Could not resolve host: repo.openeuler.org], as shown in the video.

To fix it:
edit /etc/sysconfig/network-scripts/ifcfg-enp0s3
set ONBOOT=yes

save and then reboot.

Then install DDE with command:
sudo dnf update
sudo dnf install dde
sudo systemctl set-default graphical.target
sudo reboot
After the restart is complete, use the user created during the installation process or the openeuler user to log in to the desktop.

dde cannot log in with root account.
dde has built-in openeuler user, the password of this user is openeuler.
