Script to update valetudo binary without internet access on the robot. I've only done a limited amount of testing on the script, so use it at your own risk

updateValetudo.sh

#!/bin/sh

# Set to correct arch
ARCH=aarch64

# set to ssh host e.g. root@192.168.0.17
SSH_HOST=valetudo

releaseManifest=$(wget -q https://github.com/Hypfer/Valetudo/releases/latest/download/valetudo_release_manifest.json -O -)

echo Found release $(echo "${releaseManifest}" | jq -r ".version")

releaseSum=$(echo "${releaseManifest}" | jq -r ".sha256sums.\"valetudo-${ARCH}\"")

if [[ -z $releaseSum  ]]; then
    echo Failed to get checksum from release! Exiting
    exit 1
fi

echo "Release checksum:   ${releaseSum}"

installedSum=$(ssh "${SSH_HOST}" "sha256sum /data/valetudo | awk '{print \$1}'")

if [[ -z $installedSum ]]; then
    echo Failed to get checksum from install! Exiting
    exit 1
fi

echo Installed checksum: ${installedSum}

if [[ "$releaseSum" == "$installedSum" ]]; then
    echo Valetudo already up to date!
    exit 0
fi

echo Stopping valetudo and backing up old binary

ssh "${SSH_HOST}" "killall valetudo && mv /data/valetudo /data/valetudo.old"

echo Downloading latest

wget -q -O - "https://github.com/Hypfer/Valetudo/releases/latest/download/valetudo-${ARCH}" | ssh "${SSH_HOST}" "cat > /data/valetudo"

installedSum=$(ssh "${SSH_HOST}" "sha256sum /data/valetudo | awk '{print \$1}'")

if [[ -z $installedSum ]]; then
    echo Failed to get checksum from install! Update is borked!
    exit 1
fi

echo Newly installed checksum: ${releaseSum}

if [[ "$releaseSum" != "$installedSum" ]]; then

    echo "Checksum don't match! Update is borked!"
    exit 1
fi

echo Update successful! Rebooting

ssh "${SSH_HOST}" "chmod +x /data/valetudo && reboot"
