Matt Venn · Answer

Unlikely to be git imo

Matt Venn · Answer

Much more likely a docker name issue

Matt Venn · Answer

I would just delete it and do make openlane from caravel user project

< U0172QZ342D> We faced the same issue in issue 963 I added git version requirement in readme because of this exact reason
