Same issue here on Fedora 45, python3-QtAwesome-1.4.2-4.fc45 with fontawesome-fonts-web-7.3.1-1.fc45. The cause appears to be that fontawesome-fonts-web 7.3.1 only ships .woff2 files in /usr/share/fontawesome/webfonts/ (fa-brands-400, fa-regular-400, fa-solid-900, fa-v4compatibility), so the .ttf symlinks in qtawesome/fonts/ are dangling. dnf provides finds no package providing those .ttf files. Workaround: copy the real fonts from the python-QtAwesome source RPM over the broken symlinks.

yeap, there are 3-4 open bugs due this fontawesome-fonts issue (looks like it's from version 7x. onwards) -> python-QtAwesome -> spyder

@jjames could you please take a look and fix the fontawesome-fonts package ?

thank you.

Hmmm, upstream stopped shipping TTF fonts in their release tarballs starting with FontAwesome 7. The tarballs now contain only OTF and WOFF2 fonts.

Can you use the OTF fonts instead?  They are in the fontawesome-7-brands-fonts and fontawesome-7-free-fonts packages.

I sent this PR to fix the symlink in python-QtAwesome

https://src.fedoraproject.org/rpms/python-QtAwesome/pull-request/9

or maybe just symlink the .woff to .ttf files inside fontawesome-fonts
