Implementation:

Create the update notification script:

Code:

sudo touch /usr/local/sbin/updatenotify

Code:

sudo leafpad /usr/local/sbin/updatenotify

insert:

Code:

#!/bin/bash

xhost local:$USER > /dev/null 2>&1
export DISPLAY=:0
apt-get update > /dev/null 2>&1
UPD=$(/usr/lib/update-notifier/apt-check --human-readable && echo && echo Click here to remove this message)
notify-send -i /usr/share/icons/Faenza/apps/48/system-software-installer.png -t 10 -u critical 'Install Updates' "$UPD"
exit

for message that must be clicked on to disappear.

Alternatively:

Code:

#!/bin/bash

xhost local:$USER > /dev/null 2>&1
export DISPLAY=:0
apt-get update > /dev/null 2>&1
UPD=$(/usr/lib/update-notifier/apt-check --human-readable && echo && echo Click here to remove this message)
notify-send -i /usr/share/icons/Faenza/apps/48/system-software-installer.png 'Install Updates' "$UPD"
exit

for default 5 second notification.

Code:

#!/bin/bash

xhost local:$USER > /dev/null 2>&1
export DISPLAY=:0
apt-get update > /dev/null 2>&1
UPD=$(/usr/lib/update-notifier/apt-check --human-readable && echo && echo Click here to remove this message)
notify-send -i /usr/share/icons/Faenza/apps/48/system-software-installer.png --expire-time=10000 'Install Updates' "$UPD"
exit

for 10 second notification (preferred).

Make the file executable:

Code:

sudo chmod +x /usr/local/sbin/updatenotify

save and close.

Add all users that have sudo access to /usr/local/sbin/updatenotify only.

Code:

sudo visudo

add:

Code:

$USER ALL=NOPASSWD: /usr/local/sbin/updatenotify

to the bottom of the file.

Create a cronjob as the user (to run hourly):

Code:

crontab -e

Code:

0 * * * * /usr/local/sbin/updatenotify >/dev/null 2>&1

Would like a similar notification to inform users that they can upgrade to next LL in Series.

The end product would utilize the various cron directories in /etc. hourly, daily, monthly.
It would also be accompanied by a basic config tool to choose how often you want the checks to be made.
