I'd recommend to just compile also GRASS GIS locally (which is rather
easy) to avoid a dependency hell.

See (unsorted):

- Debian: https://grasswiki.osgeo.org/wiki/Compile_and_Install#GRASS_7_on_Debian_Buster
- Ubuntu: https://grasswiki.osgeo.org/wiki/Compile_and_Install_Ubuntu#Quick_instructions
- Fedora: https://grasswiki.osgeo.org/wiki/Compile_and_Install#GRASS_GIS_7_on_Fedora
- Linux Mint: https://grasswiki.osgeo.org/wiki/Compile_and_Install#Linux_Mint
- Windows:https://grasswiki.osgeo.org/wiki/Compile_and_Install#MS-Windows
- MacOS: https://grasswiki.osgeo.org/wiki/Compile_and_Install#macOS

etc. on that Wiki page.

Most of them are copy-paste instructions.
