these 3 b+ issues you refer to were with the 4.4 kernel in 16.04 (bugs in the interaction with backported patches of the NIC driver)
... the above 18.04 should use a newer kernel (4.15 ?) which should have the necessary patches included already, this looks more like the netplan configuration was not done correctly during install ... (check /etc/netplan/ for a yaml file and take a look at https://netplan.io/ for info about how to set up its contents) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1806813 Title: Add Pi Compute Module 3 Support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/flash-kernel/+bug/1806813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
