Public bug reported: When the first DNS lookup fails with a format error (see attachment captured by Wireshark): No DNS-lookup works, even if I change to a working connection. I can't connect at all to the Internet. I need to restart the computer to get the DNS-system working again with another connection.
If I first connect to the working connection and then switches to the connection that sometimes gives format errors, the errors are ignored and the connection works. $ lsb_release -rd Description: Ubuntu 18.04.2 LTS Release: 18.04 ** Affects: ubuntu Importance: Undecided Status: New ** Attachment added: "Format error reported by Wireshark" https://bugs.launchpad.net/bugs/1820240/+attachment/5246372/+files/formaterror.pcapng -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820240 Title: dns lookup reports format error packet response To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1820240/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
