Package: aptitude Version: 0.6.3-3.2 Severity: minor Instead of -sy, I tried -s <&-, which instructs the shell to close stdin after forking and before execing. The behaviour was undesirable:
$ aptitude -s install <&- vim The following NEW packages will be installed: vim vim-common{a} vim-runtime{a} 0 packages upgraded, 3 newly installed, 0 to remove and 30 not upgraded. Need to get 7,425 kB of archives. After unpacking 28.6 MB will be used. Do you want to continue? [Y/n/?] Invalid response. Please enter a valid command or '?' for help. Do you want to continue?

On Ubuntu 10.04 (aptitude 0.4.11.11-1ubuntu10) the behaviour was even stranger -- it showed the changelog for the "check" package in my $PAGER (w3m)! lucid$ aptitude -s install <&- vim Reading package lists...
