@Markus,

You need to install coreutils package on your Linux distribution.

$ sudo apt install coreutils         [On Debian, Ubuntu and Mint]
$ sudo yum install coreutils         [On RHEL/CentOS/Fedora and Rocky Linux/AlmaLinux]
$ sudo emerge -a sys-apps/coreutils  [On Gentoo Linux]
$ sudo apk add coreutils             [On Alpine Linux]
$ sudo pacman -S coreutils           [On Arch Linux]
$ sudo zypper install coreutils      [On OpenSUSE]

I get: 

"sha256SUM: command not found"

Thanks

On Linux disks are files. (e.g. /dev/sdX) it should work. The place where it is problematic is where a compressed image is provided and then decompressed before copying to the disk.

@Charles,

The command sha256sum only check the checksum of the file, not a device or disk…

How does one indicate the device (e.g. sdb1)?

@Tfj,

Then you can run the sha256sum by mentioning the hash on the command itself and compare the results with the hash on the website as shown.

$ sha256sum ubuntu-20.10-desktop-amd64.iso 3ef833828009fb69d5c584f3701d6946f89fa304757b7947e792f9491caa270e ubuntu-20.10-desktop-amd64.iso
