Sometimes when some Ubuntu components are not up-to-date, automatic installation of Parallels Tools may fail. To ensure that all the components are up-to-date and perform the installation manually, follow the steps below:
- Run the virtual machine.
- Mount the Parallels Tools .iso by clicking Actions > (Re-)Install Parallels Tools.
- Inside the virtual machine, open Terminal and execute the following commands one by one:
sudo apt-get install dkms libelf-dev linux-headers-$(uname -r) build-essential
sudo mount /dev/cdrom /media/cdrom
- Follow the Parallels Tools Installer instructions to complete the installation.
- When the installation of Parallels Tools is complete, restart your virtual machine.
