restart your virtual machine and switch the ubuntu system to maintenance mode (this option is available on the startup menu).

then set locale to English mode en_US.UTF-8 , or to zh_CN.UTF-8 .
refer to https://www.thomas-krenn.com/.

if set to Chinese mode, you need to install at least one Chinese font. For example: 

sudo apt install fonts-wqy-zenhei

change the language to English, you should be Chinese or something else, or install a font, otherwise the display will not be normal
