*** This bug is a duplicate of bug 1756846 *** https://bugs.launchpad.net/bugs/1756846
Thanks to the investigation from Steve, it seems that during the dist- upgrade process ifupdown was removed due a transient conflict during the devel cycle. This caused it to be removed. It being removed didn't provide network. So this bug is basically a duplicate of #1756846. 17:21 < slangasek> roaksoax: according to your logs, during that upgrade the ifupdown package was removed (because of a transient conflict during the devel cycle). you do not have the ifupdown package installed. 17:22 < slangasek> roaksoax: reinstalling ifupdown will fix this, and this is basically a duplicate of LP: #1756846 ** This bug has been marked a duplicate of bug 1756846 bridge-utils incompatible with ifupdown on bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761294 Title: Network configuration doesn't survive reboots after bionic dist- upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1761294/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
