grey1beard is back !

I'd just bought a desktop for my workshop system, and already had an up-to-date Mint 19.1 installed, so I'm going ahead with that, even though Im used to Ubuntu.
I edited the line , tar.xz to tar.gx, and it's now moving on.
Fingers crossed !

gz not gx, maybe just a typo

Looking ahead, I see that the next line ends .patch.gz - perhaps that should also be patch.gx ?
Then on the next instruction to 'Extract and Patch', The same errors ?

PS just read your latest post, and I may be 'up the pole' once more !
pps Yes, gz it is

Back at the same place it seems.

Feeling out of my depth, unless I stand on tiptoe !

I tried going through the installation once more, and got further, but still not completed.
Having told terminal to 'make', in building the kernel, it returned the following

I'm quite prepared to have another attempt, but should I somehow remove/purge my earlier attempts, and if so, how?
Thanks,
John

Many thanks. I'll give that a try tomorrow.
