SOLVED: OK, I think I have fixed it. I am running Lubuntu 15.04.
My notebook is a Pentium M and I need to have the pae flag added to the cpuinfo file manually. I had done this prior to upgrade to 15.04 but it seems to have gotten removed after that. In Terminal, I first ran the following to check if the PAE flag was still in the cpuinfo file: sudo grep flags /proc/cpuinfo In the long string of output, there was no *pae* So, I followed the instructions for “Upgrading” at this webpage: https://help.ubuntu.com/community/PAE/PentiumM These instructions manually add the pae to the cpuinfo file. Then I ran an install fix: sudo apt-get install -f Then, closed Terminal and went into the software updater program, to check for any needed updates. Things updated correctly and reboot produced no more errors. Again, refer to this webpage under *Upgrading* for the Terminal commands needed: https://help.ubuntu.com/community/PAE/PentiumM -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1512016 Title: package linux-image-3.19.0-31-generic (not installed) failed to install/upgrade: subprocess new pre-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1512016/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
