Re: [Bug 1816530] Re: DNS servers are not being set in the system correctly when you upgrade from 16.04 to 18.04
True, the upgrade completed successfully but without DNS which is reasonable because I don't think that a user needs a network connection after the files were downloaded. But I experience Wi-Fi disconnects once in a while. Anyway, I tried to figure out what might be the reason for the absent of DNS. During the upgrade I choosed to keep my files when asked to keep or change to the distro one's. I tried to remember which files I kept and checked for network related files and I found that my NetworkManager.conf was different from the distro file which was copied to /etc/NetworkManager during the upgrade. My old file: [main] plugins=ifupdown,keyfile,ofono dns=dnsmasq no-auto-default=aa:bb:cc:dd:ee:ff, [ifupdown] managed=false The distro file: [main] plugins=ifupdown,keyfile [ifupdown] managed=false [device] wifi.scan-rand-mac-address=no So, I decided to use the distro file instead my old file and now the DNS works. What I see now in syslog which might be related and I don't see when I used 8.8.8.8 as a workaround is this: Oct 10 09:47:58 systemd-resolved[335]: Using degraded feature set (UDP) for DNS server a.b.c.d.
