install Arial fonts lost in latex

Today I compile a tex file , the following is a error in the file:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!
! fontspec error: "font-not-found"
!
! The font "Arial" cannot be found.
!
! See the fontspec documentation for further information.
!
! For immediate help type H <return>.
!...............................................

l.9 \setmainfont{Arial}

This font is not installed in the Debian testing , So I try to google it!
One of the answer is

 wget http://tug.org/fonts/getnonfreefonts/install-getnonfreefonts
 texlua install-getnonfreefonts
 sudo getnonfreefonts -a
 sudo getnonfreefonts-sys -a

in https://www.tug.org/fonts/getnonfreefonts/

I have done this to my computer, but it does not take effect!
Second answer is to installttf-mscorefonts-installer, but the resource requested is too slow to download!

So anyone can help me to solve this problem???
Thank you in advance!
