apt-get upgrade and yad

[misko_2083]

I've been playing with a little script to update packages.
So here is the thing. When a package manager has an exclusive lock and this script tries to start the update, it calls a function to check wheather there is a lock or not.
If there is a lock it opens a Yad progress dialog which waits until the package manager (synaptic, gdebi-gtk, aptitude, apt...) releases the lock.
Now, when I click on Cancel on that same dialog Yad kills the parent process but there is still a child process that is checking the lock.
It eventualy closes when the package manager is closed, but I wonder if there is a way to kill it along with the parent.

The problem is in function checklock. When the synaptic is running and you select the 'Update Packages' from the main dialog, click the Cancel and look for the process with htop.
Any suggestions are welcome.

# Bash/YAD Debian Package Updater based on Linux Lite update tool
# ------- Change log ------
# Switched to YAD and adapted to Debian
# Added: a main dialog loop, log, option to purge the lists, about dialog
# Added: a check for exclusive lock
# -----------------------------------
# Note:  function checklock -> if Cancel is selected while the package manager (synaptic) is open
#        Yad progress kills the parent but will not kill the child process running the exclusive lock check
#        Subshell will be running until the package manager releases the lock

Have you seen this discussion?

Will take a look at the script and try to debug as well

What do you name it?  I know I can use any, just wanting to know your naming convention

Thanks

Thank you.
I haven't came up with a name. Might as well be updater.sh as I named it here. 

I've come up with a solution. Killing all the processes with the name from basename.
Using the basename means the script name can be anything.

Hmm, yad-updater.sh would be a good name. 
Fixed the text in the progress when downloading packages. It should display the package name when downloading, but not tested yet.
So here is the whole thing

Also fixed the button name here.

Could be an issue here and there but it's updating packages.
Having an option to select which package to update appears too complicated right now. I'll skip that one because it look's like a dependancy hell to me.

Hi ~RaMich~ and welcome to VSIDO    Hi ~ RaMich ~ und willkommen bei VSIDO

I think the translation is something like:

I played with the code and broke it...  

[~RaMich~]

wenn du meinst?
teste es. irgendwo speichern, ausführbar machen und los gehts. .. sofern auch alle neuen Abhängigkeiten installiert sind.

[VastOne]

wenn du meinst?
teste es. irgendwo speichern, ausführbar machen und los gehts. .. sofern auch alle neuen Abhängigkeiten installiert sind.

if you think?
try it. somewhere save, execute and go. .. as long as all new dependencies are installed.

OK I will test it 

[VastOne]

Tested and the conversion to German works perfectly...

Good work!
