Axios You like weird coincidences? Not sure I do. I never heard of P7zip in my life when I responded to your post here, to try to confirm duplication of your stuff to help.
So I went about my business tonight. I really need the microsoft core fonts (for work) but Solus has no 3rd party page anymore (the one with the install commands) and I think Solus is out of the Microsoft font business. So I'm reading reading reading
and one fix is for someone to install P7zip so linux can extract the mscore-ttf package out of the Windows .iso. This tool was built as a linux-to-windows dealio, like Wine I gather. From Linux distro to Windows iso seems like a specialized tool indeed.
(I found what I needed at Github, no matter how sketchy and piecemeal🙂)
