#12152 Create detached signatures for the butane 0.21.0 release

Closed: Fixed with Explanation 7 months ago by kevin. Opened 7 months ago by ydesouza.

Please create detached signatures for the binaries we will upload to GitHub for the butane 0.21.0 release. This is a manual process for now, pending the automation discussed in https://pagure.io/robosignatory/issue/53 and https://github.com/coreos/fedora-coreos-tracker/issues/335.

The binaries themselves have been built in koji. Here is a small script to grab all of the rpms and the files out of the rpms and name them appropriately:

#!/bin/bash
set -eux -o pipefail

# Use the Fedora 40 key for the detached signatures
KEYTOSIGNWITH='fedora-40'

VR='0.21.0-1.fc40'
RPMKEY='a15b79cc' # Fedora 40 key

do_sign() {
    # Sign with sigul unless FAKESIGN=1
    if [ ${FAKESIGN:-0} != 1 ]; then
        sigul sign-data -a $KEYTOSIGNWITH "$1" -o "$1.asc"
    else
        echo INVALID > "$1.asc"
    fi
}

# Grab the binaries out of the redistributable rpm
rpm="butane-redistributable-${VR}.noarch.rpm"
koji download-build --key $RPMKEY --rpm $rpm
rpm -qip $rpm | grep -P "^Signature.*${RPMKEY}$" # Verify the output has the key in it
rpm2cpio $rpm | cpio -idv './usr/share/butane/butane-*'

# Rename the binaries
mv usr/share/butane/butane-aarch64-apple-darwin \
    butane-aarch64-apple-darwin
mv usr/share/butane/butane-aarch64-unknown-linux-gnu-static \
    butane-aarch64-unknown-linux-gnu
mv usr/share/butane/butane-ppc64le-unknown-linux-gnu-static \
    butane-ppc64le-unknown-linux-gnu
mv usr/share/butane/butane-s390x-unknown-linux-gnu-static \
    butane-s390x-unknown-linux-gnu
mv usr/share/butane/butane-x86_64-apple-darwin \
    butane-x86_64-apple-darwin
mv usr/share/butane/butane-x86_64-pc-windows-gnu.exe \
    butane-x86_64-pc-windows-gnu.exe
mv usr/share/butane/butane-x86_64-unknown-linux-gnu-static \
    butane-x86_64-unknown-linux-gnu

# Sign them
do_sign butane-aarch64-apple-darwin
do_sign butane-aarch64-unknown-linux-gnu
do_sign butane-ppc64le-unknown-linux-gnu
do_sign butane-s390x-unknown-linux-gnu
do_sign butane-x86_64-apple-darwin
do_sign butane-x86_64-pc-windows-gnu.exe
do_sign butane-x86_64-unknown-linux-gnu

# Fix permissions and clean up
chmod go+r *.asc
rm $rpm; rmdir ./usr/share/butane; rmdir ./usr/share; rmdir ./usr

After running this you should end up with a directory with files in it like:

$ ls -1
butane-aarch64-apple-darwin
butane-aarch64-apple-darwin.asc
butane-aarch64-unknown-linux-gnu
butane-aarch64-unknown-linux-gnu.asc
butane-ppc64le-unknown-linux-gnu
butane-ppc64le-unknown-linux-gnu.asc
butane-s390x-unknown-linux-gnu
butane-s390x-unknown-linux-gnu.asc
butane-x86_64-apple-darwin
butane-x86_64-apple-darwin.asc
butane-x86_64-pc-windows-gnu.exe
butane-x86_64-pc-windows-gnu.exe.asc
butane-x86_64-unknown-linux-gnu
butane-x86_64-unknown-linux-gnu.asc
