Installing under a user account
- Root or sudo access allows the installer to set up support services on operating systems that support services, such as Debian-based or RHEL-based systems.
- Without root or sudo access, the installer cannot set up support services because it does not have permission to create the services files.
In GUI mode if gksudo or pkexec is not installed, the installer might not present a GUI sudo prompt. Subsequently the sudo prompt appears in the shell:
