More Rocky Linux download options here: https://rockylinux.org/download/

Download

We will install Rocky Linux 8.4, you can pick the “DVD” link of the “x86_64” architecture, and download with your favourite brower.

We are downloading the Rocky Linux DVD Iso file with Chrome.

Checksum

You can get the validated ISO file checksum from the Rocky Linux website:

laptop% curl -s https://download.rockylinux.org/pub/rocky/8/isos/x86_64/CHECKSUM | grep "(Rocky-8.4-x86_64-dvd1.iso)"
SHA256 (Rocky-8.4-x86_64-dvd1.iso) = ffe2fae67da6702d859cfb0b321561a5d616ce87a963d8a25b018c9c3d52d9a4

We can generate the sha256 checksum of your ISO file downloaded locally:

laptop% sha256sum Rocky-8.4-x86_64-dvd1.iso
ffe2fae67da6702d859cfb0b321561a5d616ce87a963d8a25b018c9c3d52d9a4  Rocky-8.4-x86_64-dvd1.iso

We can compare the two values: the reference checksum from the Rocky Linux website and the generated on my computer are the same. We are good:

ffe2fae67da6702d859cfb0b321561a5d616ce87a963d8a25b018c9c3d52d9a4 = ffe2fae67da6702d859cfb0b321561a5d616ce87a963d8a25b018c9c3d52d9a4

ISO to USB key

You can pick one of these tools or use the excellent default dd command tool of your computer:

Plug your USB key and boot your computer. Depending of the default configuration, you should enable the USB boot by configuring your BIOS or pushing one function key during the boot.
