Every release is signed and checksummed; the detached signature and the checksum file accompany the ISO at the download endpoint, and the verification guide above is how you check what you got. No SBOM, package manifest or release dossier is published for this release, and no QA evidence bundle has been produced for it.

Checksum file

A verified ISO is not the same thing as a signed bootloader. This release is not Secure Boot signed, so on a machine with Secure Boot enabled the USB may simply not appear or refuse to boot. What that means and what to do about it is on Secure Boot.

Verify on Linux or macOS with:

gpg --import shadowfetch.gpg.asc
gpg --verify shadowfetch-4.1.0-amd64.iso.asc shadowfetch-4.1.0-amd64.iso
shasum -a 256 shadowfetch-4.1.0-amd64.iso

Write the ISO to a USB stick

You need an 8 GB or larger USB stick — writing the ISO erases everything on it, so back up anything you want to keep first. The easiest, hardest-to-get-wrong way is a graphical writer:

balenaEtcher
Windows, macOS, Linux
The simplest cross-platform option. Pick the ISO, pick the USB drive, click Flash. It validates the write for you.
KDE ISO Image Writer
Shadowfetch, KDE Plasma
Built right into Shadowfetch and KDE Plasma (search “ISO Image Writer” in the menu). Choose the ISO and the target USB, write.
GNOME Disks
GNOME systems
Open the USB device, use the menu’s Restore Disk Image…, and select the ISO.

Whichever tool you use, double-check you selected the USB stick and not an internal drive before you write.

Advanced: write from the command line with dd

If you prefer the terminal on macOS or Linux, dd works — but it has no undo and no confirmation.

sudo dd if=shadowfetch-4.1.0-amd64.iso of=/dev/sdX bs=4M status=progress conv=fdatasync

Replace /dev/sdX with your USB stick’s device (find it with lsblk on Linux or diskutil list on macOS). Get this wrong and dd will silently overwrite whatever disk you point it at — including the one you booted from. There is no warning and no recovery. If you are not certain which device is the USB stick, use a graphical writer above instead.
