I experienced this during the process of upgrading from 13.10 to 14.04 final beta in a terminal window using the command "sudo do-release- upgrade -d". Running the command suggested in the warning message in a console window during and after the upgrade did nothing useful. After completing the upgrade and rebooting there has been no problem and further invocations of apt-get update and apt-get upgrade have gone smoothly.
I did have one failure to boot, the very first reboot after the upgrade it appeared the video wasn't initialized or something. This may be unrelated but I summarize it here just in case. Rebooted again, chose Advanced Options, enabled network, ran dpkg several times to fix broken packages. Rebooted once more to find the wrong video mode, rebooted one final time and everything is running correctly ever since. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gdk-pixbuf in Ubuntu. https://bugs.launchpad.net/bugs/619003 Title: GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/usr/lib /gdk-pixbuf-2.0/2.10.0/loaders.cache' Status in “gdk-pixbuf” package in Ubuntu: Confirmed Status in “gdk-pixbuf” package in Debian: New Bug description: During installation of updated version of libgdk-pixbuf2.0-0 on August 10th 2010, the apt term.log contained multiple (>300) copies of the following warning: (gtk-update-icon-cache:4729): GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such file or directory Nevertheless, the file complained about exists, and is readable in gedit.
