      Hi guys, so my first question post here on ML... I have a PC build with brand new components I want ubuntu server on. Said and done, everything is running perfectly, but every time I shut it down it stops at an error "failed to finalize DM devices". By then it has shut down all Services and devices, but the power stays on. I have googled the hell out of it and there seems to be a bug in 16.04 LTS that no one has found the workaround for yet. Anyone run into this and figure it out? I don't really want to revert back to 14.04.

        I haven't seen this issue personally, but according to the Ubuntu forums it is likely CUPS that is causing the issue.

        Recommended solution, revert.

          @DustinB3403 Thanks, but no cups on the install. Just Samba and Webmin.

                From the last 3 boot/shutdowns 2 were successful (with error warning), 1 not successful. Awesome.... :rolling_eyes:

                  Is this running on bare metal or in a VM?

                        If this is a fresh install.... Does it happen with any other distros? (or Ubuntu 15?)

                          @dafyre Yes, just installed this morning, so haven't spent the time on other distros or releases. I think the most aggravating part is that it's sporadic. I would like to figure it out instead of going back a release.

                            I wonder if you could move back to an older Kernel? (assuming you've run updates)

                              @dafyre You mean like a downgrade to 14.04? AFAIK that is not possible without a clean install.

                                You should be able to, there is even a how-to.

                                  I'm talking about the Linux kernel... the 14.04 is the whole Ubuntu version... From your server run umm...

                                  uname -r
                                  

                                  should tell you the version of the linux kernel...

                                  Have you done software updates yet?

                                    @dafyre Ah, gotcha. Yes, it is a 16.04.1 installation and is completely updated. I am running release 4.4.0-31-generic.

                                      I'm fresh out of ideas for the moment.

                                        @dafyre no problem, too much time on this would be a waste, it is a fresh install. Going back to 14.04. Just would have liked to figure out what it is, kind of feels like giving up... 😉

                                          lol. Yeah. I'm having an issue in my Tumbleweed install... also a fresh install, so I know the feeling.

                                            Ubuntu 16.04 shutdown issues here, too. But it fixed itself after it updated.
