This will be changed in a future update, but until then it could be helpful.
If you are like me and love the Mate-Menu then maybe you also have install Synaptic. But whenever you click on the Package Manger link in the menu the Ubuntu Software Center starts. So I wanted to change that and it wasn’t as difficult as I thought it to be.
Fire up the terminal, backup /usr/lib/ubuntu-mate/mate-menu/plugins/system_management.py and open it with your favorite editor. I will use geany.
cd /usr/lib/ubuntu-mate//mate-menu/plugins/
sudo cp system_management.py system_management.py.bak
sudo geany system_management.py
And search for the following lines (lines 143-146):
if os.path.exists("/usr/bin/software-center"):
Button2.connect( "clicked", self.ButtonClicked, "/usr/bin/software-center" )
elif os.path.exists("/usr/bin/synaptic-pkexec"):
Button2.connect( "clicked", self.ButtonClicked, "/usr/bin/synaptic-pkexec" )
Replace them with the following:
if os.path.exists("/usr/bin/synaptic-pkexec"):
Button2.connect( "clicked", self.ButtonClicked, "/usr/bin/synaptic-pkexec" )
elif os.path.exists("/usr/bin/software-center"):
Button2.connect( "clicked", self.ButtonClicked, "/usr/bin/software-center" )
Log out and in again. The next time you click in the Package Manager button it will start Synaptic. The most beautiful thing is, whenever you uninstall Synaptic it will automatically start the Ubuntu Software Center again.
