For me this bugs occurs whenever I try to specificed a IP instead of using DHCP.
THe NM crash and dont save nothing, so it continues with DHCP, this is a showstopper in large enterprises where it is not permited DHCP Servers for security reasons. The temporary solution is to complete remove NM and manual configure the interface. -- NetworkManager assert failure: ERROR:nm-device.c:2754:dispose: assertion failed: (s_ip4) https://bugs.launchpad.net/bugs/436654 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
