I mounted Tails OS (booted through ISO file) on Virtual Box. The default OS display looks ugly and I couldn't mount Guest Additions through Optical drive as I mounted OS through the same. So, I uploaded Guest Additions.iso file in Google drive and downloaded in VM. When I try to install it, I got following error

Guest Addition Installation Error

  • Looks like you need to specify a path to install Vbox Guest Additions; i recommend using /usr/bin

You should run 'VBoxLinuxAdditions.run' file, not the autorun.sh.

Syntax: bash VBoxLinuxAdditions.run
