Try

sudo apt install nvidia-prime

Also, you may need to do as described here:

sudo systemctl disable nvidia-fallback.service

Add

nouveau.blacklist=1

in /etc/default/grub in the line GRUB_CMD_LINUX_DEFAULT

sudo update-grub

Install bbswitch-dkms (sudo apt install bbswitch-dkms), and add bbswitch to /etc/modules.

I had the same issue with my gtx 1050 on Ubuntu 18.04.

Install the nvidia driver (in my case nvidia-driver-390)

Open /etc/default/grub and removed all options in GRUB_CMDLINE_LINUX_DEFAULT and in GRUB_CMDLINE_LINUX

Run sudo update-grub and then restart.

Now you can run sudo prime-select intel with no errors. Also you can use nvidia settings GUI to define which gpu to use under PRIME Profiles
