If "Failure to download extra data files" fails, the error message disappears too fast

[Steven Pemberton]

Often after a software update, you get the dialogue window "Failure to download extra data files".

For instance: "The following packages requested additional data downloads after package installation, but the data could not be downloaded or could not be processed.

flashplugin-installer"

The dialogue box has a button "Run this action now".

If you click on it, a terminal window pops up, and runs some commands.

There are two problems:

1) If the process fails, the terminal window closes before you get a chance to read what the problem was, and so it is very hard to find out what you need to solve.

2) If the terminal window succeeds succeeds, the dialogue box remains visible, giving the same message, and so you don't know if the problem has now been solved or not, and whether to press the "run this action now" button again.
