Despite my comment above, I still have this problem when using netplan.
Here is my /etc/netplan/config.yaml (external IP quatrains have been
changed), the setup is that enp8s1 provides internet access (with metric
49) and enp7s0 provides local lan access *and* (with metric 51) fallback
internet
I have the same problem and every time I upgrade systemd, it kills my
network access to the server. I therefore had to disable automatic
updates and always run a shutdown -r 10 command before upgrading

I changed my networking setup to use netplan and the problem
disappeared.

Having the exact same issue with ubuntu 20.04. Has anyone found a work
around for this rather annoying issue?

Title:
Updating systemd kills network on bionic
Status in linux package in Ubuntu:
Can confirm the same behaviour on my systems too. Updating systemd
recently caused the entire routing table to be dropped (I had console
access and was able to confirm no routes - not even loopback worked). In
normal operation I see:
>ip route show
default via 10.0.0.1 dev eno1 src
I'd like to also confirm this bug, which we've been experiencing for the
past few months since we first setup an 18.04 image for our deployment
portal.
Initially I thought the cause MAY have been from us using ifupdown (we
have to as our vCenter instance hasn't been upgraded to 6.5.x or 6.7
where
Some more info:
- The machine is a Virtualbox ubuntu bionic, and I have a snapshot before the
upgrade, so I can reproduce it
- I'm using ifconfig instead of netplan, because I need a ppp interface (for
pppoe)
- I have an /etc/network/interfaces file
- it seems that the interface through
Also I see this in the logs, but maybe not related (why can't I edit my
comments?)

And logging in on the console the apt process was waiting on for some answers:

The following packages were automatically installed and are no longer required:

I could only resolve the ssh issue with killing the apt process, and restarted
networking.
This is a pretty bad issue imho. Upgrading packages through ssh should not
disconnect the session, but even if it is, upgrading the systemd package should
not result in not being able to log back in ever
I recently installed a fresh system with 18.04 as well and have
experienced this exact issue when attempting to "apt dist-upgrade" from
ssh. In the two instances where systemd was being updated (a few weeks
ago and today), my ssh connection was dropped and I'm unable to re-
connect to the server.
Today, just another "apt-get upgrade":

I examined /var/log/dpkg.log. There is no pause in there. The complete
upgrade process looks pretty normal to my. So I guess it is just a
network configuration issue during the upgrade that prevented my
terminal session from getting updated.
