I was able to fix that, with the following steps, first of all; I had virtualbox 5.0 beta installed, then I removed it used the following command sudo dpkg -r virtualbox
I figured out if I only use "dpkg -r" or "dpkg --remove" it will not run "postrm". it means that the configuration files remain the same. but using "dpkg --purge" removes the package and it runs "postrm". it will clear out all the configuration conflicts. After that I was able to do a clean install using "sudo apt-get install virtualbox". I hope this comment help. cheers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1417722 Title: package virtualbox-guest-utils 4.3.18-dfsg-2ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1417722/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
