Hey @burhandodhy, the previous versions of Local used a virtual machine in VirtualBox to navigate around the ports that XAMPP would have used simultaneously. Local v5 (which is the first version that supports Linux) does away with needing VirtualBox. This has a lot of performance and development advantages but it does introduce port conflicts that were side-stepped before. I know the team is working on making this easier to navigate in future releases but right now, you will have to shut down Local or XAMPP because they will conflict in the ports that they need.
