dotcover not work in linux

i'm running the latest version of dotcover console command line tool in linux.

  chmod +x /opt/dotcover/dotCover.sh
  chmod +x /opt/dotcover/runtime-dotnet.sh
 chmod +x /opt/dotcover/linux-x64/dotnet/dotnet

/opt/dotcover/dotCover.sh cover --Instance=1 --targetExecutable="/opt/binar/Flexem.CorporationService.HttpApi.Host.dll" --output="report.html" --reportType="HTML"

I got this error:

[JetBrains dotCover] Failed to start coverage analysis. Unable to start profiling.

Permission denied

How do i  fix this problem? It works smoothly on windows OS.
