Aucune version de Signal n’est packagée officiellement pour Fedora (ou dérivés RedHat). Voici un script pour récupérer le dernier .deb et le convertir en .rpm (après quelques correctifs), pour ensuite être installé sous Fedora:
#!/bin/bash
DISTRIB=xenial
LAST_VERSION=`curl -s https://updates.signal.org/desktop/apt/dists/$DISTRIB/main/binary-amd64/Packages | grep ^Version: | grep -v beta | awk '{print $2}' | sort -V -r | head -n1`
if [ -z $LAST_VERSION ]; then
echo "No version found"
exit 1
fi
CURRENT_VERSION=`rpm -q --qf "%{VERSION}\n" signal-desktop`
if [ $? -ne 0 ]; then
CURRENT_VERSION=0.0.0
fi
echo Current version: $CURRENT_VERSION
echo Available version: $LAST_VERSION
if [[ $CURRENT_VERSION = $LAST_VERSION ]]; then
echo Up to date
exit 0
fi
TMP_DIR=/tmp/signal-desktop_${LAST_VERSION}_amd64
TMP_FILE=${TMP_DIR}.deb
WORK_DIR=$TMP_DIR/signal-desktop-${LAST_VERSION}
echo Temporary file: $TMP_FILE
echo Temporary directory: $TMP_DIR
echo RPM working directory: $WORK_DIR
mkdir -p $TMP_DIR
test -f $TMP_FILE || curl https://updates.signal.org/desktop/apt/pool/main/s/signal-desktop/signal-desktop_${LAST_VERSION}_amd64.deb -s -o $TMP_FILE
test -d $WORK_DIR || (cd $TMP_DIR && sudo alien -r -g $TMP_FILE)
if [ $? -ne 0 ]; then
exit 1
fi
sudo sed -i 's/^Summary: $/Summary: signal-desktop/' $TMP_DIR/signal-desktop-${LAST_VERSION}/signal-desktop-${LAST_VERSION}-2.spec
(cd $TMP_DIR && sudo rpmbuild --buildroot $WORK_DIR -bb $WORK_DIR/signal-desktop-${LAST_VERSION}-2.spec && sudo dnf install ../signal-desktop-${LAST_VERSION}-2.x86_64.rpm)
if [ $? -ne 0 ]; then
exit 1
fi
rm $TMP_FILE
sudo rm -R $TMP_DIR
exit 0
