Physical machine installation Ubuntu 20.04

1, System installation

An error occurs when installing the system using the USB flash disk. The reason is that the boot mode used in the previous installation of windows 10 is legacy, which needs to be changed to uefi. Press the shortcut key to enter the BIOS and modify the boot option.

If no modification is made, an error will be reported: error: symbol 'grub_calloc' not found.

The modification options are as follows

1. Change the source of Linux

#Backup original source

This completes the installation of Sogou Pinyin, enjoy!!!

3. Screenshot tool

I personally recommend using flameshot, which has more complete functions than the tools provided by the system.

Installation method: after ubuntu adds the source, directly install apt:

sudo apt install flameshot

Set shortcut keys:
