yesterday i was trying to build a custom iso of trusty i386. during the first attempt, towards the end (after i decided to mark all upgrades and install them) the error message appeared-after repeated attempts to fix the broken packages and -f options to remove and install the package i had to give up the project. here is the message from the terminal

# sudo dpkg --configure -a

I've just encountered this problem when trying to make my own custom Ubuntu 14.04 distribution in a fakechroot, and I came up with a solution which seems to work. In the (admittedly dated) Ubuntu Live CD Customization guide, there is a bug involving initctl mentioned. I used the same approach to prevent invoke-rc.d from running, which the configuration of libpam-systemd uses. invoke-rc.d is a utility for starting and stopping initd scripts, which don't need to be running in the chroot:

dpkg-divert --rename --add /usr/sbin/invoke-rc.d
ln -s /bin/true /usr/sbin/invoke-rc.d
#Run apt-get, dpkg etc...
rm /usr/sbin/invoke-rc.d
dpkg-divert --rename --remove /usr/sbin/invoke-rc.d

With the diversion in place, invoke-rc.d always returns success and doesn't do anything, which is exactly the desired behaviour inside a chroot.

  • I did exactly as the code in his answer, albeit, I've put them into a script. I also added a similar code, but for /usr/sbin/grub-probe instead of /usr/sbin/invoke-rc.d. This allows grub-install to run in the chroot environment. N.B.: I haven't fully tested what the side-effects are.

is a well known bug: (see Bug #1325142 on Launchpad); I met this problem too while I was building my own Live in chroot and I solved it (if "solved" can be the right word ... let's create a new word, say "workarounded") this way:

in chroot, after having finished installing everything, I've stated not to update libpam-systemd:

echo "libpam-systemd  hold"|dpkg --set-selections

then I've dist-upgraded my distro without (obviously) getting any error and finally I've built my live DVD.

To test if my workaround was good, I've installed trusty on a VM from that iso, logged in and from shell I've revoked the directive on iso about not to upgrade libpam-systemd:

sudo -i
echo "libpam-systemd install"|dpkg --set-selecions

and finally I've dist-upgraded again the brand new system: no errors.

I think it's a problem happening just in chroot environment.

Cheers,

Silvia
