I'm having trouble to install updates, because it pop-up a window requiring to authenticate. and the problem is, I don't know it.
Thanks!

Based on your question is hard to understand otherwise than that installing or removing an app is asking you to enter your login password. See, Ubuntu requires you to give permission for every action or task involving changes to your system, so simply use your login pass-phrase when installing or removing an app.
