This is the output of the command ""sudo apt update && sudo apt upgrade"". See picture, please. Fortunately I use Trisquel 9 mini (32bit)

Seems like the update changed /etc/systemd/resolved.conf default from DNSSEC=no to DNSSEC=allow-downgrade.

You might like uncomment DNSSEC and set it back to
DNSSEC=no

As some ISP are not DNSSEC capable, or you might like to add a third party DNS Public Server, then restart systemd-resolved

sudo systemctl restart systemd-resolved.service
Or reboot.

Is this change specific to Nabia? I am writing this message from a laptop using Aramo, every line in /etc/systemd/resolved.conf is commented out.

How can I uncomment DNSSEC? The file is read only.

You need administrative privileges, as granted by sudo:
$ sudo pluma /etc/systemd/resolved.conf
Here I put Pluma, MATE's text editor. Replace it with your favorite text editor.
