I am trying to install my Graphics Driver for my Radeon RX 460 and I am stuck at extracting the content of the amdgpu-pro-16.40-348864.tar.xz file. I run ​tar -Jxvf amdgpu-pro_16.30.3-348864.tar.xz from the terminal (I used cd command to navigate to the file) and I get

termozour@termozour-ubuntu:~/Desktop$ ​tar -Jxvf amdgpu-pro-16.40-348864.tar.xz

xz: (stdin): File format not recognized

tar: Child returned status 1

tar: Error is not recoverable: exiting now

I have checked if xz tools is installed, and it is, and updated to the latest version. How can i extract it so I can install it ?

EDIT1: I tried downloading the file again several times, and I still got the same problem. I emailed AMD regarding the issue, and they have forwarded my email to a more specialized staff, to fix my issue.

I can boot Ubuntu if my GPU is either unplugged from the MoBo or if it's disabled in UEFI BIOS.

  • should I send an Email to AMD about the issue ? – TermoZour Nov 28 '16 at 19:09

The archive file is corrupted (probably during an interrupted download). These things happen. Download it anew and try again. If the same problem persists please edit your question to clarify that.

Update: If the file stays corrupted even after a re-download the problem may lie on AMD's side, i. e. they published a broken archive file. This is purported by the fact that you're not the only one with this issue.

  • I have edited the question regarding the file download. Thank you for suggesting it. – TermoZour Dec 1 '16 at 6:15

If you are running a GUI just find the file with File Manager and double-click it.
The archive manager should open it for you, and then you can extract.

  • If I open the archive with Nautilus, it displays an error trying to open the archive, and an empty window which is actually the archive – TermoZour Dec 1 '16 at 6:12
