ubuntu 18.04 dpkg--configure-a

I got this trying to install from the software catalog with the sort of briefcase icon. It told me the install failed and i should issue this, which does not mean a thing to the terminal. this is on an EeePC which often has strange things happen.

You got what? (what is “this”?)
What were you trying to install?
What does a “briefcase icon” mean on your system?
What kind of Linux are you running?

Issue what?

It doesn’t mean anything to me either :confused:

An ancient machine that was never designed to run Linux.

I’m sure it does. So why are you telling us this? How can we help?
