I have the same problem with today's last upgrade

i386

[Brian Homeyer (bhomeyer-alsysinc)]

Same here. i386

[Wade Allen (wade-cbcspringfield)]

Same problem here.

[Mike Hix (mike-musl)]

Just installed a fresh copy of ubuntu gutsy. This issue causes synaptic to crash as well.

[Mike Hix (mike-musl)]

Is there a quick workaround? Can I hold back the cups packages so that I can continue the upgrade?

[Brian Curtis (bcurtiswx)]

Same error here. inspiron 6000 1.2GB RAM

[Lukas Sabota (punkrockguy318)]

Workaround:
sudo dpkg -i --force-overwrite /var/cache/apt/archives/cupsys_1.3.2-1ubuntu4_i386.deb

[StephanBeal (sgbeal)]

i thought i'd be clever and work around the problem by removing the package before doing the upgrade. WRONG! Don't do 'apt-get remove libcupsys2'!!!!! It will remove your whole KDE installation plus many other apps (emacs, openoffice, and firefox, in my case).

[Stephen Monteith (stephen-monteith)]

The latest package cupsys_1.3.2-1ubuntu5_i386 solved the issue. I consider this bug solved as far as I'm concerned.

Thanks for the quick work on this.
