Unable to extract .tar.xz files

Question

I am new to Linux and I am trying to install AMD drivers on my system. For this I downloaded the file from AMD website. It is called amdgpu-pro-17.30-465504.tar.xz. In the website it says that I have to extract the file using the following command

tar -Jxvf amdgpu-pro-17.30-450654.tar.xz

But when I do this, I am getting the following error.

username@Lenovo:~/Downloads$ tar -Jxvf amdgpu-pro-17.30-465504.tar.xz
xz: (stdin): File format not recognized
tar: Child returned status 1
tar: Error is not recoverable: exiting now

How can I install extract it? What is the cause of this error?

Solution 1

xz-utils can extract xz compressed files

Install it with the following command:

sudo apt install xz-utils -y

Then use it as below to extract your file:

xz -d amdgpu-pro-17.30-450654.tar.xz

Solution 2

tar -xvf amdgpu-pro-17.30-450654.tar.xz

No need for J in the beginning! With J you are filtering it, but usually it's not neccessary.

Are you sure it was a .xz file? The error you're getting means xz doesn't think it's an xz file.

What happens with the command tar -xvf amdgpu-pro-17.30-450654.tar.xz (without the J)? Could the file be damaged or given the wrong extension?

Same error again

use file amdgpu-pro-17.30-465504.tar.xz to check what it is.

[Admin]

@Rinzwind Now gives the output saying : amdgpu-pro-17.30-465504.tar.xz: data

It the file fully downloaded yet?

[Admin]

@mikewhatever Yes it is

[muru]

If file says it's just data, the download was probably corrupted. Download again

Can you expand on this answer a bit?

When I remove the J, I get a new error... "tar: This does not look like a tar archive".
