I think I founded why happening this exception. After installation, I removed the mate-welcome package. Because my system not present following files, happened the reported exception: /usr/bin/synaptic-pkexec, /usr/bin/software-center, /usr/share/applications/ubuntu-mate-software.desktop Real my machine not installed Synaptic, software-center or the mate-welcome package, with ships the ubuntu-mate-software utility. If I installing for example the synaptic package, the exception is not happening. Same result if I turning off the Show package manager related GSettings preference the mate-plugin related, following the GSettings schema and name: Schema name: org.mate.mate-menu.plugins.system_management Setting name: show-package-manager Default value: true
Following code part affected the exception related if one of the examined packages not installed: def do_standard_items( self ): if ( self.showPackageManager == True ): if os.path.exists("/usr/bin/synaptic-pkexec"): Button2 = easyButton("synaptic", self.iconsize, [_("Package Manager")], -1, -1 ) Button2.connect( "clicked", self.ButtonClicked, "/usr/bin/synaptic-pkexec" ) elif os.path.exists("/usr/bin/software-center"): Button2 = easyButton("softwarecenter", self.iconsize, [_("Package Manager")], -1, -1 ) Button2.connect( "clicked", self.ButtonClicked, "/usr/bin/software-center" ) elif os.path.exists("/usr/share/applications/ubuntu-mate-software.desktop"): Button2 = easyButton("system-software-install", self.iconsize, [_("Package Manager")], -1, -1 ) Button2.connect("clicked", self.ButtonClicked, "/usr/bin/ubuntu-mate-welcome --software-only") Button2.show() self.systemBtnHolder.pack_start( Button2, False, False, 0 ) self.mateMenuWin.setTooltip( Button2, _("Install, remove and upgrade software packages") ) Attila -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575058 Title: If I using Mate Menu applet my panel, always me presents an Unbound Local Error exception To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mate-menu/+bug/1575058/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
