Public bug reported:
There are still occurrences of this service breaking down.
At some moment the service just stops working correctly and is not able
to recover.
I can reset the service by restarting it:
systemctl restart systemd-resolved.service
I've also tried to set the caching off, but it still fails on me
occasionally (on 18.04 as well).
There is a local DNS in the network, I would like to directly use that in stead
of:
nameserver 127.0.0.53
Example:
geus@desk-02:~$ ssh smb-01
ssh: Could not resolve hostname smb-01: Temporary failure in name resolution
...
root@desk-02:/home/geus# systemctl restart systemd-resolved.service
root@desk-02:/home/geus# nslookup smb-01
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
Name: smb-01.lan
Address: 192.168.178.39
...
geus@desk-02:~$ ssh smb-01
geus@smb-01's password:
