I'm a little new at this so not sure if this was the right way, but i added xenial-proposed and selected the 3 samba updates.
libwbclient0:amd64 (2:4.3.9+dfsg-0ubuntu0.16.04.2, 2:4.3.9+dfsg- 0ubuntu0.16.04.3), samba-libs:amd64 (2:4.3.9+dfsg-0ubuntu0.16.04.2, 2:4.3.9+dfsg-0ubuntu0.16.04.3), libsmbclient:amd64 (2:4.3.9+dfsg- 0ubuntu0.16.04.2, 2:4.3.9+dfsg-0ubuntu0.16.04.3) This is a on a fresh install of 16.04 with all current updates. Problem is resolved for me and no errors or other odd behavior. I don't use samba shares though. Someone in another thread seems to think it is an ISP problem. Running nautilus now no longer causes 100% on one core, and my computer is running a lot cooler in general. It's a passive cooled system so quite noticeable! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572260 Title: gvfs-smb-browse hogs CPU after only opening nautilus To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1572260/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
