Boot option guide
Verify your download
Please verify all downloads!
Alongside the actual download files (ISO, netboot, sources), the Grml mirrors publish the extra files SHA256SUMS-2024.12 and SHA256SUMS-2024.12.gpg.
The SHA256SUMS-2024.12 file contains checksums for all available release files.
The SHA256SUMS-2024.12.gpg file provides the GnuPG signature for that file.
Once you have SHA256SUMS-2024.12 and SHA256SUMS-2024.12.gpg in the same directory as your Grml downloads, verify the checksum file via:
gpg --keyid-format long --verify SHA256SUMS-2024.12.gpg SHA256SUMS-2024.12If you don't have our GnuPG signing key (key ID 0x96A87872B7EA3737, fingerprint 33CC B136 401A FEC8 43A3 8763 96A8 7872 B7EA 3737), run:
gpg --keyid-format long --keyserver hkps://keys.openpgp.org --recv-keys 0x96A87872B7EA3737Finally verify the checksum of your Grml downloads, via:
sha256sum --ignore-missing -c SHA256SUMS-2024.12Source code
