I ran dpkg --get-selections | grep linux-image to find old installations of the kernel images such as: linux-image3.19.0.15-generic the purged them with this command
sudo apt-get purge linux-image-3.19.0-15-generic I did this for all old linux-images in the list from the dpkg --etc command above I deleted all but the current and the next most current, there were two linux-image-extra...etc that needed to be purged as well. These were listed with a "deinstall" parameter in the dpkg --etc list. I am not sure why those needed special attention but the rest auto purged the linux-image-extra...etc packages with the single: sudo apt-get purge linux-image-3.19.0-xx-generic command I then upgraded to 15.10 and I no longer have the "Reached target Shutdown" hang issue...at this time, caveat it hangs for a few seconds but not indefinitely for me. These are the only images currently installed now: dpkg --get-selections | grep linux-image linux-image-3.19.0-49-generic install linux-image-4.2.0-27-generic install linux-image-extra-3.19.0-49-generic install linux-image-extra-4.2.0-27-generic install linux-image-generic I would be interested if others have tried this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1464917 Title: reboot hangs at 'Reached target Shutdown' To manage notifications about this bug go to: https://bugs.launchpad.net/systemd/+bug/1464917/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
