Ubuntu – How to you install new fonts to LibreOffice snap

That's weird. I just tried with the same font (mingliu.ttc) and it worked fine in LibreOffice on Ubuntu 10.10.

There might be a problem with your font cache.

Try running sudo fc-cache -f -v. This will rebuild the cache.

I've found a solution for this problem. To do that you have to paste the fonts in the directory

~/.local/share/fonts

It's important to mention here that, normally, you can't see the folders which started with a dot(.)(in ubuntu folders started with . are hidden folders). To see these folders press ctrl+h or click view > show hidden files.

Now if you don't have a folder named fonts in ~/.local/share/, then create one and paste your desired fonts in that folder.

This solution worked for me; hope it can help others.
