Hello, https://bugs.launchpad.net/ubuntu/+source/synaptic/+bug/1766161
has been marked a duplicate of this bug. This issue may have been reported a long time ago, but it is still current problem. A simple solution would be a pop-up window in synaptic when you lock an application, to warn the user that "...this loçk will only work in synaptic; if you use any other software to upgrade your computer, please engage the lock in that application as well..." Would that work?
