I see the same on 14.04, even without "-" on the su. The test also lacked the -c for the command, and "-" would need to be at the end or specified as "-l". Also we might execute something that doesn't add output, to easen debugging (/bin/true)
Anyway - that just refines the simple test, the issue is there as reported. Simplified test: su testuser -c "/bin/true" -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to shadow in Ubuntu. https://bugs.launchpad.net/bugs/1534090 Title: 'call to get_tasks_recursive failed' errors from su Status in shadow package in Ubuntu: Confirmed Bug description: In Ubuntu 14.04 all of a sudden I'm seeing these two error messages coming up every time I use su -, whether in a script or interactive shell: call to remove-on-empty (freezer:0) failed: invalid request call to get_tasks_recursive failed: Invalid arguments received in reply Example and how to reproduce: root@localhost:~# su - test "echo hello" call to remove-on-empty (freezer:0) failed: invalid request -su: echo hello: No such file or directory call to get_tasks_recursive failed: Invalid arguments received in reply call to get_tasks_recursive failed: Invalid arguments received in reply root@localhost:~# su - test call to remove-on-empty (freezer:0) failed: invalid request test@localhost:~$ This only seems to affect Ubuntu 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shadow/+bug/1534090/+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
