Thank you for taking the time to report this issue and help to improve Ubuntu.
You say that this happened during installation. Which install method were you using? Is this problem reproducible with later versions of Ubuntu? This bug was automatically filed against the pam package, but it probably needs to be assigned to the installer. ** Changed in: pam (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/589438 Title: package libpam0g 1.1.1-2ubuntu3 failed to install/upgrade: - hit ctrl-C because it FROZE for hours on this package while installing -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
