Title:
  sudo: pam_mount.c:417: modify_pm_count: Assertion `user != ((void
  *)0)' failed. Aborted

Status in “pam” package in Ubuntu:
  New

Bug description:
  Pam will not let me clean the apt cashe or install non-Ubuntu (3rd
  Party) packages.

  Xubuntu 12.04 Beta 2 (development branch)

  libpam-modules 1.1.3-7ubuntu2 <-----------------------------------------------------------------------------| 
  libpam-modules-bin 1.1.3-7ubuntu2 <------------------------------------------------------------------------|
  libpam-mount 2.10.2build1 <-------------mainly in this package but I susspect that it is  in --->|
  python-pam 0.4.2-12.2ubuntu4             the modules as well.
  libpam-cap 1:2.22-1ubuntu3
  libpam-ck-connector 0.4.5-2
  libpam0g 1.1.3-7ubuntu2
  libpam-smbpass 2:3.6.3-2ubuntu1
  sadms 2.015-repack-0ubuntu2
  winbind 2:3.6.3-2ubuntu1
  libpam-winbind 2:3.6.3-2ubuntu1

  I expected it to clean my cache it did not there are still files in
  it.

  Returned this error in terminal when using sudo apt-get clean:
  sudo: pam_mount.c:417: modify_pm_count: Assertion `user != ((void *)0)' failed. Aborted

  It may affect encrypted volumes as well and also when ever you enter your password for sudo, OpnePGP, Software Center, or Synaptic. Also possibly Update Manager. 
  Also what I did to fix it was to disable and then re-enable pam-mount with sudo pam-auth-update.
  But may reoccur on next session.
