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 and SHA256SUMS.gpg.
The SHA256SUMS file contains checksums for all available release files.
The SHA256SUMS.gpg file provides the GnuPG signature for that file.
Once you have SHA256SUMS and SHA256SUMS.gpg in the same directory as your Grml downloads, verify the checksum file via:

gpg --keyid-format long --verify SHA256SUMS.gpg SHA256SUMS

If 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:// --recv-keys 0x96A87872B7EA3737

Finally verify the checksum of your Grml downloads, via:

sha256sum --ignore-missing -c SHA256SUMS
