Hi, I'm trying to build in Ubuntu 22.04 I tried build-dep lilypond but I get a fairly vague reply from it
$ sudo apt-get build-dep lilypond Reading package lists... Done E: You must put some 'deb-src' URIs in your sources.list Does anyone have a quick breadcrumb or two to share with me about how to resolve this please? Cheers L -- Luca Fascione
