network-manager 0.9.8.8-0ubuntu7 amd64 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1310746 Title: NetworkManager wired ethernet times out waiting for dhcp on 14.04 trusty tahr Status in “network-manager” package in Ubuntu: Confirmed Bug description: I'm experiencing dhcp timeouts on 14.04 that I didn't experience in earlier releases (13.10 and 12.04 are in use in the office). Others in my office have similar complaints that "wired ethernet stops working in 14.04" which all equate to a dhcp timeout. When switching back to 13.10 dhcp works flawlessly. network-manager 0.9.8.8-0ubuntu7 (the current version on trusty) contains the following changelog: * debian/tests/nm: Bump DHCP timeouts from 15 to 20 seconds, something in the stack got even slower as it used to be. * debian/tests/nm: With the patch in 0.9.8.8-0ubuntu5, interfaces with PE disabled still get a temporary IP. Disable that check for now. -- Martin Pitt <_____...@ubuntu.com> Wed, 09 Apr 2014 15:41:11 +0200 I don't think increasing the timeout in the test in order to get it to pass is the correct approach. It's likely masking the underlying issue that we're experiencing. ------ 1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu Description: Ubuntu 14.04 LTS Release: 14.04 2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center network-manager: Installed: 0.9.8.8-0ubuntu7 Candidate: 0.9.8.8-0ubuntu7 Version table: *** 0.9.8.8-0ubuntu7 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status isc-dhcp-client: Installed: 4.2.4-7ubuntu12 Candidate: 4.2.4-7ubuntu12 Version table: *** 4.2.4-7ubuntu12 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status isc-dhcp-common: Installed: 4.2.4-7ubuntu12 Candidate: 4.2.4-7ubuntu12 Version table: *** 4.2.4-7ubuntu12 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status 3) What you expected to happen Ethernet to "just work" 4) What happened instead Wired ethernet times out waiting for a dhcp connection.
