Public bug reported:
Binary package hint: aptitude
When a particular package or package archive has been assigned a
negative priority in /etc/apt/preferences, the documentation in manual
page apt_preferences states that those packages are never installed.
When this case occurs, a sudo user trying to install such a package, aptitude
crashes with a segmentation fault.
Example: if /etc/apt/preferences contains:
Package: *
Pin: release v=7.04
Pin-Priority: -1
Package: *
Pin: release v=6.10
Pin-Priority: 1001
the following command crashes:
sudo aptitude install autopsy/feisty
while this one succeeds:
sudo apt-get install autopsy/feisty
(this a case where the package exists in both archives, but the same problem
arises with a package which exists only in feisty, like say update-inetd)
I suppose the documentation should be understood as "are never (automatically)
installed" but whatever, aptitude should address this case more gracefully...
I'm using current edgy versions for both aptitude and apt-get:
$ aptitude -F%p%20v search ~i\(aptitude\|~Rdepends:aptitude\)
apt 0.6.45ubuntu14
aptitude 0.4.1-1.1ubuntu7
libc6 2.4-1ubuntu12
libgcc1 1:4.1.1-13ubuntu5
libncursesw5 5.5-2ubuntu1
libsigc++-2.0-0c2a 2.0.16-3
libstdc++6 4.1.1-13ubuntu5
** Affects: aptitude (Ubuntu)
Importance: Undecided
