Integrate version upgrade

[boredsquirrel]

This should work

#!/bin/bash
source /etc/os-release

read -p "What version of Fedora are you upgrading to? (37, 38 etc): " NEXT_VERSION
echo "Upgrading to Fedora $NEXT_VERSION from Fedora $VERSION_ID"
read -p "Press any key to continue...." 

sudo rpm-ostree rebase fedora:fedora/$NEXT_VERSION/x86_64/$VARIANT_ID

To do that, the main file could be modified to add upgrade if a new version of Silverblue is available. Adding the code below to silverblue-update should work, for x86_64 version:

# Check for the most recent stable release and upgrade if available
NEW_VERSION=$(ostree remote refs fedora | grep x86_64/silverblue | grep -v rawhide | sort -V | tail -n 1)
CURRENT_VERSION=$(rpm-ostree status --json | jq -r '.deployments[0].origin')

if [ "$NEW_VERSION" != "$CURRENT_VERSION" ]; then
    if ! /usr/bin/rpm-ostree rebase "$NEW_VERSION" > /var/run/silverblue-update/rebase.log 2>&1; then
        logger "silverblue-update: System rebase (upgrade) failed"
        notify_all "Could not upgrade to the new system release!"
        WITH_ERRORS="yes"
    else
        logger "silverblue-update: System rebase (upgrade) completed successfully"
        notify_all "System successfully upgraded to the new release!"
    fi
else
    logger "silverblue-update: No new system release available"
fi
