I have this issue, it appears to be caused by Network manager not being able to cope with previously defined debian interface files.
I saw this for the first time when upgrading/installing via net- installer to jaunty. lspci, lshal and nm-tool info attached . my /etc/network/interfaces is just auto eth0 etc defaults as created by deb-installer. Only weird thing about my network is that I run ipv6 along side .( which on a side note the deb-installer does not support) ** Attachment added: "lspci, lshal and nm-tool" http://launchpadlibrarian.net/22404423/logs.gz -- [MASTER] [WORKAROUND] "Offline Mode" feature fails to detect proper online state for networks that are managed outside of network manager. https://bugs.launchpad.net/bugs/191889 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
