[Aptitude-devel] Bug#822560: aptitude: Pressing "q" to quit after installation leaves a black terminal

[Ralf Jung]

Package: aptitude
Version: 0.8-1
Severity: normal

Dear Maintainer,

I am using Terminator as my terminal emulator. Since the latest update, aptitude
tells me I can press "q" to Quit directly after packages have been
installed. However, if I do that, the screen is left entirely blank and there is
no reaction to typing. Only if I press Ctrl-C, I can see the terminal again (and
some garbage that I have input in the mean time).

If, instead of pressing "q", I press Ctrl-C directly when I get the prompt that
asks me to hit Enter, then aptitude quits just fine.

I know little about the interaction of terminal programs and terminal emulators,
so I started by reporting the bug here.

Kind regards,
Ralf
