A bit of a misunderstanding here I'll break it down:

Choose to update or not > this refers to the original first dialogue, line 32:

Code:

zenity --question --title="Linux Lite Updates" --window-icon="/usr/share/icons/zenity-llcc.png" --text="We will now fetch the Updates list.\n\nClick Yes to continue or No to abort."

This is kept because someone may have clicked on the wrong item in the Menu, or decided against updating.

updates will run > self explanatory.

have the option at the end to view the log which should reside in /var/log - the default dialogue at the end of the file:

Code:

PROCEED=$(zenity --question --title="$APPNAME Updates" --window-icon=/usr/share/icons/zenity-llcc.png --text="Updates have finished installing.\n\nWould you like to view the $APPNAME Updates log?"; echo $?)
if [ ${PROCEED} -eq 1 ]; then
   zenity --info --title="$APPNAME Updates" --window-icon="${INSTALL_ICON}" --text="$APPNAME Updates Complete."
   exit;
else
   zenity --text-info --ok-label="Quit" --cancel-label="Cancel" --title="Updates Log" --width=700 --height=300 --filename="/var/log/llupdates.log"
fi

So we want to retain the original first dialogue and original logging method If there is a bug, then the intuitive place to look is /var/log.

Latest iteration:

- Added line 91
- Reverted to original log and first dialogue processes
