Installing Microsoft fonts is simple through the terminal on Debian-based distributions.
Why are Microsoft fonts not installed?
Microsoft fonts like Times New Roman, Arial, etc. are not open source. Because of licensing issues, most linux distributions opt to exclude proprietary software.
Install Microsoft fonts using Terminal / CLI
When the EULA agreement appears, press tab and enter on
<Yes> on the “Do you accept the EULA license terms?” screen.
Refresh the font cache.
If the EULA is mistakenly rejected, reinstall.
