** Description changed: On Ubuntu 20.10, if a user creates an interface that is unmanaged by NetworkManager (e.g. a tunnel interface), NetworkManager will overwrite it's DNS config on systemd-resolved. A fix for this already exists upstream - https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/4ddfc5c14b6f82d802988332d92a7e05b18d1ff0 - To reproduce, one can create a WireGuard interface via `wg-quick` and - assign DNS servers via systemd-resolve, observe that `systemd-resolve - --status` contains the servers set previously and then suspend the - machine and wake it up and then check that `systemd-resolve --status` - output no longer contains the previously set servers. + To reproduce, one can create a WireGuard interface via `wg-quick` and assign DNS servers via systemd-resolve, observe that `systemd-resolve --status` contains the servers set previously and then suspend the machine and wake it up and then check that `systemd-resolve --status` output no longer contains the previously set servers. + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu50.5 + Architecture: amd64 + CasperMD5CheckResult: skip + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 20.10 + InstallationDate: Installed on 2020-12-01 (69 days ago) + InstallationMedia: Ubuntu 20.10 "Groovy Gorilla" - Release amd64 (20201022) + Package: network-manager 1.26.2-1ubuntu1 + PackageArchitecture: amd64 + ProcVersionSignature: Ubuntu 5.8.0-43.49-generic 5.8.18 + RfKill: + + Tags: groovy + Uname: Linux 5.8.0-43-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo + _MarkForUpload: True + nmcli-nm: + RUNNING VERSION STATE STARTUP CONNECTIVITY NETWORKING WIFI-HW WIFI WWAN-HW WWAN + running 1.26.2 connected started full enabled enabled enabled enabled enabled ** Attachment added: "CRDA.txt" https://bugs.launchpad.net/bugs/1915153/+attachment/5461672/+files/CRDA.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915153 Title: NetworkManager will change DNS config via systemd-resolved of unmanaged interfaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1915153/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
