Checking and modifying the file and directory permissions where Tableau Server is being installed When encountering a permissions issue during the installation of Tableau Server on Linux, the first and most relevant step is to check and modify the file and directory permissions where Tableau Server is being installed. Permission issues are common in Linux environments and ensuring that the Tableau Server installation directory has the correct permissions is essential for a successful installation. Option A is incorrect because reinstalling the Linux operating system is an excessive measure for resolving permission issues. Option C is incorrect as increasing hardware resources does not address permission-related installation failures. Option D is incorrect because changing the file system is unrelated to permission issues and is not a standard trouble-shooting step for Tableau Server installation problems.
