git clone -b v3.2 https://github.com/frescobaldi/frescobaldi.git pip install qpageview cd frescobaldi ./frescobaldi
I still hope for a native apt installation, but until then with this solution, I can use custom fonts, any lilypond version I want, call git from Scheme and the "real files on disk" are opened when clicking inside Frescobaldi.
Thank you!
