GUI Updates script

(1/11) > >>

Jerry:
Hi folks,

I would like some volunteers to try this update script I have been working on and off for some months now.

This would require you to create this file first so that there is no interruption in the update process:
(source http://raphaelhertzog.com/2010/09/21/debian-conffile-configuration-file-managed-by-dpkg/)


--- Code: ---sudo leafpad /etc/apt/apt.conf.d/local
--- End code ---


--- Code: ---Dpkg::Options {
   "--force-confdef";
   "--force-confold";
}
--- End code ---

save and close.

Here is the script:


--- Code: ---leafpad ~/updatestest
--- End code ---

copy into the following, then save and close, and make executable:


--- Code: ---#!/bin/bash
#-----------------------------------------------------------------------------------------
# Name: Linux Lite Updates
# Description: A GUI tool to easily install Updates in Linux Lite.
# Authors: Misko_2083, Jerry Bezencon
# Date: Nov 20th, 2014
# Website: https://www.linuxliteos.com
#-----------------------------------------------------------------------------------------

# Kill off any package managers that may be running
sudo killall -9 synaptic
killall -9 gdebi-gtk

# Need a check here to see if any updates are available, if there are none, script pops up dialog box saying 'No Updates Available'


# Erase existing available info
sudo dpkg --clear-avail

# Linux Lite default dialog icon
ic="/usr/share/icons/zenity-llcc.png"

# Get list of available updated packages then populate them to /tmp/updateslist
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."
   if [ "$?" -eq "0" ];then

x=$( stdbuf -oL /bin/bash \-c '(sudo apt-get update \-y )' 2>&1 |
stdbuf -oL sed -n -e '/\[*$/ s/^/# /p' -e '/\*$/ s/^/# /p'|
zenity --progress --title="Updating package information..." --pulsate \

       exit 0

Please make sure all software installation programs like
<b>Synaptic Package Manager</b> and <b>Gdebi</b> are closed before proceeding.

When you click on <b>Yes</b>, this window will close and the updates will begin.

# Halt updates script if user selects Cancel

       exit 0

# Continue script if no halt

        zenity --question --title="$APPNAME Updates" --window-icon="${INSTALL_ICON}" --text="${INSTALLER_TITLE}"

                if [ "$?" -eq "0" ]; then

                                if [ "${PIPESTATUS[0]}" -ne "0" ]; then
                       
                                        zenity --error \
                                        --title="Error" --text="$APPNAME Updates have failed."
                                        exit 0
                                fi

                else

                                        exit 0
                fi

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 --title="Updates Log" --width=700 --height=300 --filename="/var/log/llupdates.log"
fi

exit 0


--- End code ---

Then open terminal and run:


--- Code: ---gksudo ./updatestest
--- End code ---

and let me know how you get on.

Thanks :)

I'm going to run this on 2.2 Final on my own computer for several months until 2.4 is released to see if it stands the test of time. If this works well and is stable, I hope to include it in 2.4 next year, being such a critical piece of software, it has to work well over a long period of time.

I would be happy too help with the script test; however, I am unable to do so because since I installed the updates on my Dell D620, that you did the remote install on (11/06/14) I have no wireless access too the network. I tried the on board help too locate a fix or a method of trouble shooting. Failing too find a fix I did as you advised and posted my problem on the forum but to date haven't received a reply. With God's help I am doing my best too find out why installing the updates would wipe out my wifi access too the network and as soon as I find the answer I will post it and should you still need a script tester be more than happy too help. God bless you.
tnx john

Scott:
@Jerry - Testing the script now. I'll have some feedback soon.

Scott:
The script is running well for me (LL 2.2/64 Beta on VBox). Possibly one small issue (see note at bottom). After running the new script(updatestest) the original script "install updates" will generate an error:



Commenting out these in "install updates" will fix it or at least stop the error.
killall -9 synaptic
killall -9 gdebi-gtk

Some troubleshooting I tried
logout/login didn't help
reboot didn't didn't help

Note. I say this is a possible issue because when this script is released I assume the orginal script "install updates" will be removed.
