Reverting util-linux/bsdutils to the previous version doesn't help so maybe it's not even script's fault. tail/coreutils hasn't been update in a long time so I'm not sure who's fault it is. I can reproduce the problem with kernel 4.4.0-9-generic and 4.4.0-10-generic. $ lsb_release -rd Description: Ubuntu Xenial Xerus (development branch) Release: 16.04 $ apt-cache policy util-linux bsdutils coreutils util-linux: Installed: 2.27.1-4ubuntu1 Candidate: 2.27.1-4ubuntu1 Version table: *** 2.27.1-4ubuntu1 500 500 http://archive.ubuntu.com/ubuntu xenial-proposed/main amd64 Packages 100 /var/lib/dpkg/status 2.27.1-3ubuntu1 500 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages bsdutils: Installed: 1:2.27.1-4ubuntu1 Candidate: 1:2.27.1-4ubuntu1 Version table: *** 1:2.27.1-4ubuntu1 500 500 http://archive.ubuntu.com/ubuntu xenial-proposed/main amd64 Packages 100 /var/lib/dpkg/status 1:2.27.1-3ubuntu1 500 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages coreutils: Installed: 8.25-2ubuntu2 Candidate: 8.25-2ubuntu2 Version table: *** 8.25-2ubuntu2 500 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: util-linux 2.27.1-4ubuntu1 ProcVersionSignature: Ubuntu 4.4.0-10.25-generic 4.4.3 Uname: Linux 4.4.0-10-generic x86_64 NonfreeKernelModules: zfs zunicode zcommon znvpair zavl ApportVersion: 2.20-0ubuntu3 Architecture: amd64 CurrentDesktop: Unity Date: Fri Mar 4 15:14:15 2016 SourcePackage: util-linux UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1553353/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
