Ubuntu 18, unable to install xelatex

I'm trying to install xelatex using

sudo apt install texlive-xetex

but I'm getting these errors.

Err:1 bionic/main amd64 texlive-latex-base all 2017.20180305-1 403 Forbidden [IP: 103.123.234.254 80]
E: Failed to fetch 403 Forbidden [IP: 103.123.234.254 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

I have already tried running apt-get update and with --fix-missing flag but it didn't solve the issue.

Can somebody please tell me how to go about this. I'm a newbie ubuntu user.

Thanks!

You seem to be behind some firewall, that doesn't allow you to reach Ubuntu repositories. You need to check your ISP and/or change Ubuntu mirror.
