Auto update

Description

Create a script for automatic binary update.

Who's implementing?

• [ ] I'm willing to implement this feature myself

The problem

I use the portable version of the https://github.com/clickot/ungoogled-chromium-binaries

It is tedious to have to manually update the binaries, so I have created a script to do it automatically.

The problem is that my bash/shell skills are limited and while it may be a solution for me I'm not sure I can maintain a stable version.

The idea is to create a wrapper in bash that checks for new updates. I share my script.

Possible solutions

My installation is in "/opt/ungoogled" so to run the browser I do "/opt/ungoogled/chrome-wrapper" I have created a second script as a wrapper "chrome-wrapper-updater":

#!/bin/bash

./updater >> ./updater.log &
./chrome-wrapper "$@"

So to run the browser I do: /opt/ungoogled/chrome-wrapper-updater

The code of the "updater" script is as follows:

#!/bin/bash

echo $(date)

DIR_INSTALL="/opt/ungoogled"
DIR_TMP="./tmp"
DIR_TMP_UPDATER="${DIR_TMP}/ungoogled-chromium-updater"
FILE_CURRENT_VER="./updater-current-version"
FILE_LAST_CHECK="./updater-last-check"
REPO_URL="https://api.github.com/repos/clickot/ungoogled-chromium-binaries/releases/latest"
REPO_KEY=".assets[].browser_download_url"
REPO_TYPE="linux.tar.xz"
REPO_LINK=""
REPO_VER=""
CURRENT_VER=$(head -n 1 $FILE_CURRENT_VER)
NOW=$(date +%s)
EVERY=$((60 * 60 * 24 * 7))
LAST_CHECK=$(head -n 1 $FILE_LAST_CHECK)
NEXT_CHECK=$(($LAST_CHECK + $EVERY))

if [[ $NOW -gt $NEXT_CHECK ]]; then
    echo "Check new version"
    REPO_LINK=$(curl ${REPO_URL} | jq -r ${REPO_KEY} | grep ${REPO_TYPE})
    REPO_VER=$(awk -F "/" '{print $(NF-1)}' <<< "$REPO_LINK")
    echo $NOW > $FILE_LAST_CHECK

    if [ $CURRENT_VER != $REPO_VER ]; then
        echo "Has new version: ${REPO_VER}"
        kdialog --title "Ungoogled Chromium Update" \
                --yesno "New version (${REPO_VER})\nUPDATE?" 0 0
        ans=$?
        if [ $ans -eq 0 ]
        then
            echo "User accepts the update: ${REPO_VER}"
            mkdir -p ${DIR_TMP}
            rm -r ${DIR_TMP_UPDATER}
            mkdir -p ${DIR_TMP_UPDATER}
            mkdir -p ${DIR_TMP_UPDATER}/${REPO_VER}
            curl -L -o ${DIR_TMP}/ungoogled-chromium-${REPO_VER}_tar.xz ${REPO_LINK}
            tar -xf ${DIR_TMP}/ungoogled-chromium-${REPO_VER}_tar.xz -C ${DIR_TMP_UPDATER}/${REPO_VER}
            NEW_VER_DIR=${DIR_TMP_UPDATER}/${REPO_VER}/$(ls -AU ${DIR_TMP_UPDATER}/${REPO_VER} | head -1)
            cp -r $NEW_VER_DIR/* $DIR_INSTALL
            echo $REPO_VER > $FILE_CURRENT_VER
            echo "Updated to: ${REPO_VER}"
            kdialog --title "Ungoogled Chromium Update" \
                --sorry "Restart Ungoogled Chromium is required"
        else
            echo "User reject the update"
        fi    
    else 
        echo "No new version"
    fi
fi

Finally with the help of stackoverflow :-) I've created a pretty "decent" script:

https://github.com/TheNocoder/ungoogled-updater

This may be of interest to: @clickot

@TheNocoder Bring this up with the packager, not on this repo's issue tracker. The purpose of ungoogled is to not phone home to ANYBODY including the packager, if they want to deviate from that goal it's on them. At any rate, using AppImage has this functionality with something like appimaged; so no need to re implement it yourself; and personally I prefer to use flatpaks as these are truly "portable" and run even without glibc on host machine (they have autoupdate functionality via DE integration)

Ok, thanks

@TheNocoder This might be a good candidate for contrib repo.

@TheNocoder Feel free to submit your script into contrib repository if you wish.
