Inkscape is one of the first things I install when I install Ubuntu. But it lacks some features, which is very telling: I'm far from being a graphic designer.
I miss more programmer oriented features; I work a lot generating SVG on the fly or loading it and applying CSS classes to it, and Inkscape only gets me to the prototype phase.
I use it in Windows too; the Windows support is frequently even better than Ubuntu (I blame non-LTS and snaps).
It is a real pity Inkscape's development is not nearly as fast as other projects (Blender, for example). I assume is a lack of funding issue; I don't know why some projects got so much donations and others so few. Having strong corporate or non profit sponsor love seems a main point.
I wish you the best. We need a really strong open source vector drawing application, be it Inkscape or not.
