Here is a bash script for Debian/Ubuntu (and possibly other Linuxes) that installs the non-free MS Office fonts, which came with Office 2007 and Windows 7 by extracting them from a freely available legacy PowerPointViewer.exe. Notably, this collection includes Calibri and Cambria, default fonts used in many MS Office documents.
Usage:
curl -s https://raw.githubusercontent.com/VentoZwerg/MSOfficeFonts/refs/heads/main/fontinstaller.sh | bash
Have fun!
