Public bug reported: At least in my case, name resolving did not work after upgrading from precise to trusty.
I fixed it manually with: cd /etc sudo ln -s /run/resolvconf/resolv.conf . There was no resolv.conf in /etc/ otherwise, but there was a /etc/resolv.conf.old which was a similar symlink to /run/. In case this cannot be reproduced, it's possible I've created the problem myself, but I cannot say for sure if I've touched /etc/resolv.conf somehow. So please check /etc/resolv.conf* before and after dist-upgrade, and the functionality of the network. ** Affects: resolvconf (Ubuntu) Importance: Undecided Status: New ** Tags: dist-upgrade precise -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1308378 Title: No working network (= name resolving) after 12.04 LTS -> 14.04 LTS upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/1308378/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
