networkmanager problems for me started with sendmail. I tried removing sendmail using aptitude but the problems continued. Prior to removal KNetworkManager would be in a loop trying to a bring a device up.
There looks to have been quite a few "hook" scripts lying around after removal causing networkmanager issues when trying to complete a dhcp transaction example log messages: Sep 11 10:53:01 localhost avahi-daemon[4905]: New relevant interface eth0.IPv4 for mDNS. Sep 11 10:53:01 localhost avahi-daemon[4905]: Registering new address record for 192.168.0.17 on eth0.IPv4. Sep 11 10:53:01 localhost dhclient: bound to 192.168.0.17 -- renewal in 586988 seconds.

Sep 11 10:54:37 localhost NetworkManager: <information>^IDevice eth0 activation scheduled... manually ifup/down ing the device works fine. I manually removed the following hook scripts: /etc/dhcp3/dhclient-exit-hooks.d /etc/network/if-up.d/sendmail /etc/network/if-down.d/sendmail and everything back to normal. I think the sendmail package should do this automatically on removal ? -- sendmail spews out error messages at boot https://bugs.launchpad.net/bugs/43752 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
