I have the same (or a similar) problem on a system with a wired ethernet connection.
Using the debug-shell I found that the shutdown was hanging on a call of /bin/sh /sbin/resolvconf -d enp0s25.inet Here enp0s25 is the ethernet interface. It has a static configuration that contains "dns-nameservers" and "dns-search" lines. Adding some diagnostic output to /sbin/resolvconf I found that it seems to hang in the case statement that spans lines 31 to 37. After some trial and error I change the pattern in line 36 from ~* to '~'* With this change shutdown now proceeds smoothly. I'm not an expert shell programmer, so I don't know why the change has this effect. Looks almost like some obscure dash bug to me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1594658 Title: diskless setup with nfs mounted home hangs on shutdown/reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/1594658/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
