Public bug reported:
Mint 19 (Ubuntu Bionic)
Laptop so Using NetworkManager, and connecting wirelessly to LAN
Upgraded from Mint 18.3 so using resolvconf...
Versions:
network-manager: 1.10.6-2ubuntu1.1
resolvconf: 1.79ubuntu10.18.04.3 or 1.79ubuntu10.18.04.2
systemd: 237-3ubuntu10.15
dns is specified in NetworkMananager as 192.168.2.1
the dns is a router, and has static ips assigned to certain hosts on my lan...
$cat resolv.conf
nameserver 127.0.0.53
search phs
options edns0
$ nslookup phspi05
Server: 127.0.0.53
Address: 127.0.0.53#53
** server can't find phspi05: SERVFAIL
If I explicity specify the dns:
$ nslookup phspi05 192.168.2.1
Server: 192.168.2.1
Address: 192.168.2.1#53
Non-authoritative answer:
Name: phspi05
Address: 192.168.2.35
I get the correct ip address...
Same with dig...
I would expect that the nameserver set in network-manager would be
used....
>From tail of $ systemd-resolve --status
Link 2 (wlp2s0)
Current Scopes: DNS
LLMNR setting: yes
MulticastDNS setting: no
DNSSEC setting: no
DNSSEC supported: no
DNS Servers: 192.168.2.1
DNS Domain: phs
So the dns address had been picked up from NetworkManager, but
apparently is not being used...
Thought it might be related to this bug:
https://bugs.launchpad.net/ubuntu/bionic/+source/resolvconf/+bug/1817903
So installed the proposed fix, but no change. I also tried removing
package resolvconf, again no change...
