if you want to install the Intel driver, you just go to the intel download page (as explained in dozens of other hashcat forum posts):

Show me the intel download link for my driver.

RE: No devices found/left - philsmd - 06-09-2020

it's directly linked in the above thread:
linux: https://registrationcenter-download.intel.com/akdlm/irc_nas/vcp/15532/l_opencl_p_18.1.0.015.tgz
windows: https://registrationcenter-download.intel.com/akdlm/irc_nas/vcp/13794/opencl_runtime_18.1_x64_setup.msi

RE: No devices found/left - Glanman - 06-09-2020

Now, how to install driver in the command terminal (root)

RE: No devices found/left - philsmd - 06-09-2020

Code:
cd Downloads/
tar xzf l_opencl_p_18.1.0.015.tgz
cd l_opencl_p_18.1.0.015/

sudo ./install.sh

The installer will tell you if you have installed all the packages that are needed (prerequisites), otherwise you will get an error or warning.

You can actually ignore the too new Ubuntu version or similar warnings, in most of the cases it will work anyway.

but the other requirements are of course needed like build tools etc (build-essential, gcc, and some libs)

RE: No devices found/left - philsmd - 06-14-2020

The downloaded file l_opencl_p_18.1.0.015.tgz defintiely contains an installation file called "install.sh" within the archive.

If you would have extracted the tgz file correctly with "tar xzf l_opencl_p_18.1.0.015.tgz" as I told you above, you could see and run the installation file (install.sh) perfectly fine.

This is getting ridiculous here, we can't really explain here how you download and run a simple installation file on linux. We can't really holding hands with users that are still learning the very basic usage of their operating system. hashcat is an advanced password cracking tool. You should be able to run a simple program on the command line, for sure.

Maybe you should use windows instead, if you are completely new to linux and unable to run a simple installation script or follow simple instructions. hashcat also works perfectly fine on windows (and macOS).
