Public bug reported: I've upgraded a server via `do-release-upgrade` from Ubuntu Bionic to Focal. It was ENI configured (since Ubuntu 12.04 Precise):
``` auto lo iface lo inet loopback # The primary network interface iface eth0 inet manual # The primary bridge interface auto br0 iface br0 inet static address 10.230.71.10 netmask 255.255.248.0 gateway 10.230.64.1 bridge_ports eth0 dns-nameservers 10.230.64.1 ``` and I lost SSH access to the system after the upgrade was completed because bridge-utils was removed during the last upgrade phase: ```Remove obsolete packages? 187 packages are going to be removed. ... Removing bridge-utils (1.6-2ubuntu1) ... ``` I think the reason was because `bridge-utils` was automatically installed, probably via `libvirt-bin`, but is this correct - a automatically package cleanup happening in an "obsolete removal" phase? ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1937869 Title: not able to SSH access a server after bridge-utils was removed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1937869/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
