the ubuntu 18.04 desktop will not boot, possibly because the configuration of the graphical desktop was damaged while installing the remote desktop.

because baidu is not specific error files and related configuration. You can only delete the desktop system.

then the problem came, sudo apt install ubuntu-desk reported dependency problems, not to install.

this installation should be OK, but TAB to OK, press ENTER, error:

tasksel aptitude failed (100)

is just another round of rummaging, but the good news is that something is wrong with the source of LINUX.

command-line switch:

CD/etc/apt/

vi sources.list
