OS: Ununtu 20.3 LTS - Kernel: 5.4.0-109-generic

Software: Power Profiler launched through nRF Connect for Desktop v3.11.0

Hardware: Power Profiler Kit II

Problem: Cannot connect to PPK2

When I open Power Profiler I get an error: Failed to get the library versions: JLINKARM_DLL_COULD_NOT_BE_OPENED (Origin: "Failed to get module versions.")

Linux itself picks up the device as follows:
