Also, your DpkgTerminal log contains the following: Cannot open pixbuf loader module file '/usr/lib/x86_64-linux-gnu/gdk- pixbuf-2.0/2.10.0/loaders.cache': No such file or directory This likely means that your installation is broken. Try running the command gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache to make things work again for the time being. You might want to fix that up as well. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ca-certificates in Ubuntu. https://bugs.launchpad.net/bugs/1766293 Title: package ca-certificates 20180409 failed to install/upgrade: installed ca-certificates package post-installation script subprocess returned error exit status 1 Status in ca-certificates package in Ubuntu: Confirmed Bug description: This happened while I tried to upgrade to 18.04 from 17.10 , on 23rd April, 3 days prior to official launch.
