I just had this problem when I enabled Defaults mail_always
in sudoers. Other sudo commands worked fine, but when doing any variation of 'sudo su -' or 'sudo su $USER', the sytem would echo 'logout' on first keypress. Could be unrelated, but still gathering information. -- after sudo su (su -), gnome-terminal [or a virtual terminal "-bash"] "exit"s ("logout"s) with any single keypress https://bugs.launchpad.net/bugs/224802 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
