I am/was also affected by this bug and can confirm that it is caused by leftover files from a former sendmail installation. Because of this, I'll add the sendmail package to the bug.
Reinstalling sendmail removed the bug. Doing an "apt-get purge" on all sendmail-related packages also removed the bug (and the offending files). @ amichair Thank you for figuring this out! You probably saved me much time! ** Also affects: sendmail (Ubuntu) Importance: Undecided Status: New ** Changed in: sendmail (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385709 Title: network-manager service doesn't start at boot time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1385709/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
