If am interested in the installation of Source-Sans-Pro adobe font which can be procured from this location: https://github.com/adobe-fonts/source-sans-pro
According to the documentation given on the page, this requires the
makeotf CLI, for installing the fonts from source.
According to the Adobe website, https://www.adobe.com/devnet/opentype/afdko.html, makeotf is part of AFDKO toolkit, which can be installed using
pip as mentioned in https://github.com/adobe-type-tools/afdko.
makeotf command is still not available on the shell.
PS: The source sans pro is available as OTF on github, but LibreOffice fails to recognise the OTF, and does not show it in the list of available fonts, even if
fc-cache -fv is run both as an administrator and a user.
