GUI Updates script

[anon222]

Thanks misko, a good quick fix there, What we need long term is a if-else statement that suppresses any errors

Here you go, pall.

Code:

#!/bin/bash

bold=`tput bold`
normal=`tput sgr0`

echo "${bold}**********************"
echo "Linux Lite 2.0 Updates"
echo "**********************${normal}"
echo ""
echo "Linux Lite will now search for updates for your computer."
echo "Once installed, your computer will be up to date."
echo "Simply follow the onscreen instructions."
echo ""
echo "Please enter your password to continue..."
if [ "$(pidof synaptic)" ]
then
    sudo killall -9 synaptic
else
    echo""
fi
if [ -z "$(pgrep gdebi-gtk)" ]
then
    echo ""
else
    killall -9 gdebi-gtk
fi
sudo apt-get update && sudo apt-get upgrade
echo ""
echo "Updates complete."
echo "This window will now close."
sleep 5

Beautiful misko! I'll upload the new deb's soon

[valtam]

New versions uploaded, credits to misko in the updates script.

First post script updated too.

[anon222]

Made some changes to the script.
Added: A check to see if any updates are available, if there are none, script pops up a dialog box saying 'No Updates Available'.
Changes: Script opens a list of available updates.
Note: The list of packages that have been kept back is not displaying.

You can.

[valtam]

Some nice additions there misko I think we should remove the checklist though, new folk could interrupt this incorrectly.

[valtam]

If you still want to use the existing Menu, Favorites, Install Updates entry to try the new beta method, here's how.

1) Open a  terminal do:

Code:

sudo cp ~/updatestest /usr/scripts

2) Then go to Menu, Settings, Main Menu. Highlight Install Updates in the right hand pane and click on Properties. Change the Command to:

Code:

gksudo /usr/scripts/updatestest

Now the new GUI will run from the Menu. To go back to the stock way of doing Updates, simply replace:

Code:

gksudo /usr/scripts/updatestest

with

OK, checklist is removed
Some minor improvements to the script.
First open sinaptic and/or gdebi-gtk to test this.

Here you've used the title to give info on the next step

Code:

zenity --text-info --title="List of available Updates - Click OK to continue or Cancel to stop the update process" --width=700 --height=300 --filename="/tmp/updateslist "

There is another approach
I've used stream editor in the script to insert two lines into /tmp/updateslist

Code:

#Insert text into  /tmp/updateslist
sed -i -e '1 i\#########                     List of available Updates                                           ##############' -e '1 i\#########  Click OK to continue or Cancel to stop the update process         ##############' /tmp/updateslist

[valtam]

I think I prefer the existing method of handling the gdebi/synaptic check, it's simpler and quicker.
Also running your new code I still get the 'List of available Updates - Click OK to continue or Cancel to stop the update process' existing dialog, not your new one, but this time it's empty when there are lots of updates for my machine:
