[Aptitude-devel] Bug#751117: aptitude segfaults when trying to acquire root powers via sudo

[Jose Antonio Ortega Ruiz]

Package: aptitude
Version: 0.6.11-1
Severity: important

I've got a local configuration file in ~/.aptitude/config with the
contents:

  aptitude::Keep-Unused-Pattern "";
  aptitude::Delete-Unused-Pattern "";
  aptitude::Suppress-Read-Only-Warning "true";
  aptitude::Get-Root-Command "sudo";


and my user belongs to the sudoers group, and sudo is configured so
that that user does not need to type her password when executing sudo
commands.  This setup has been working for years, and broke a few days
ago.

When i do a U in aptitude to update the package list, i get the usual
dialog asking me if i'd like to change the root account.  When i
accept by hitting return on the "Become root" button, aptitude
immediately segfaults.

I've tried to eliminate the possibility of a ncurses problem by using
xterm instead of rxvt, and i have the exact some behaviour in both
emulators.
