Hello Guido, Thank you for opening this bug and helping make Ubuntu better.
As far as I can remember, Ubuntu has been using kill from the procps package, not coreutils. On Cosmic and 16.04 (the only machines I have access to right now), /bin/kill is being provided by procps: cerdea@piatam:$ dpkg -L coreutils|grep kill 1 $ dpkg -L procps|grep kill /bin/kill /usr/bin/skill /usr/share/man/man1/kill.1.gz /usr/share/man/man1/skill.1.gz /usr/bin/pkill /usr/share/man/man1/pkill.1.gz It is probable that this is also your case, but before changing the package in the bug I would like you to check. * man kill should tell you if it is coreutils or not; * apt-file search bin/kill will return you all packages that deploy "bin/kill" (note that we are only looking for /bin/kill). Please report back, and we will then act as needed. ** Changed in: coreutils (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to coreutils in Ubuntu. https://bugs.launchpad.net/bugs/1791983 Title: kill -TERM exitcode regression 16.04 Status in coreutils package in Ubuntu: Incomplete Bug description: I had a regression error in one of my testsuites. https://github.com/gdraheim/docker-systemctl-replacement/issues/43 After investigating I did find that the command "kill -TERM" behaves different in Ubuntu 16.04 in comparison to all other Ubuntu versions and in comparison to all other tested Linux distributions (opensuse,centos). ====> "kill -TERM" does report an exitcode=0 (OK) where it should say failed. Note that the testsuite of coreutils does define a behaviour of not-ok at http://git.savannah.gnu.org/cgit/coreutils.git/tree/tests/misc/kill.sh There you can see # params required returns_ 1 env kill || fail=1 returns_ 1 env kill -TERM || fail=1 However this is the result tested with the available docker images == kill ubuntu:14.04 => 1 ubuntu:16.04 => 1 ubuntu:18.04 => 1 ubuntu:18.10 => 1 == kill -TERM ubuntu:14.04 => 1 ubuntu:16.04 => 0 ubuntu:18.04 => 1 ubuntu:18.10 => 1 I am attaching the testscript that shows the results above.
