Jerry:
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."
--- End code ---
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
--- End code ---
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.

OK how about now? First dialog is removed.

Jerry:
I certainly appreciate the work thats gone into the log file changes, but I think there is now too much user interaction.
Ideally, they will:
Choose to update or not > updates will run > have the option at the end to view the log which should reside in /var/log.
anon222:
Yes, but we could show only the first 64 characters of the strings. It doesn't need to be 64 you can tweak that at your end.
