What should I do if the Debconf window appears when installing software in the Ubuntu Software Center?

Ubuntu Software Center is a Ubuntu system-specific software application that can be used to install and uninstall software. When using the Ubuntu Software Center to install an application, "Debconf runs on Ubuntu" window, causing the software installation to fail. What should I do?

After checking something and didn't find a solution, I planned to switch to apt-get installation. But this time it is prompted "There is a package that is not fully installed or uninstalled", and then every time you use the apt-get command, you will try to link edelivery.Oracle.com, and wait a long time after the link times out. Probably will output such a message:

Oracle JDK 7 is NOT installed.

dpkg: Error processing oracle-java7-installer (--configure):

Child process The post-installation script has been installed and returned error number 1

An error occurred during processing:

oracle-java7-installer

So I guessed these two “ cards The situation of living in rdquo; should be the same reason. And the error is displayed as oracle-java7-installer, so it should be wrong when I installed openjdk7 with ubuntu software center (I don't know why), so I just need to delete all the jdk things~

Then, enter the Synaptic Package Manager, search for jdk by name, and then delete the installed packages found (if you are not sure which one is deleted, reinstall it) ). As shown (this is refilled, after a)

The above method is to solve the after Debconf Ubuntu Software Center appears, you will need to enter the package management jdk delete, delete it and then This window will not appear when you install the uninstall software.
