Public bug reported:
systemd 237-3ubuntu10 from bionic
There is no /etc/netplan/* file.
I'm getting some sort of a loop when systemd-resolved tries to resolve
the hostname of my canonistack instance:
ubuntu@bip:~$ systemd-resolve bip.lcy02.canonistack
bip.lcy02.canonistack: resolve call failed: All attempts to contact name
servers or networks failed
systemd-resolved debug output loops over like this:
Transaction 36341 is now 19121.
Cache miss for bip.lcy02.canonistack IN A
Transaction 19121 for <bip.lcy02.canonistack IN A> scope dns on */*.
Using feature level UDP+EDNS0 for transaction 19121.
Sending query packet with id 19121.
Processing incoming packet on transaction 19121. (rcode=SUCCESS)
Server feature level is now lower than when we began our transaction.
Restarting with new ID.
Transaction 19121 is now 17157.

Packet capture shows a loop like this:
13:38:32.293524 IP 10.55.32.54.53786 > 10.55.32.1.53: 46096+ [1au] A?
bip.lcy02.canonistack. (50)
13:38:32.293753 IP 10.55.32.1.53 > 10.55.32.54.53786: 46096* 1/0/0 A
10.55.32.54 (55)
13:38:32.294026 IP 10.55.32.54.53786 > 10.55.32.1.53: 64494+ [1au] A?
bip.lcy02.canonistack. (50)
13:38:32.294249 IP 10.55.32.1.53 > 10.55.32.54.53786: 64494* 1/0/0 A
10.55.32.54 (55)
I'm going to attach the full debug output, and the pcap file.
