Resolv.conf not changing

[bigverm23]

I tried these steps multiple times :

Deactivate DNSStubListener and update the DNS server address. Create a new file, /etc/systemd/resolved.conf.d/adguardhome.conf (creating the /etc/systemd/resolved.conf.d directory if needed) and add the following content to it:

[Resolve]
DNS=127.0.0.1
DNSStubListener=no
Specifying 127.0.0.1 as the DNS server address is necessary because otherwise the nameserver will be 127.0.0.53 which doesn't work without DNSStubListener.

Activate a new resolv.conf file:

mv /etc/resolv.conf /etc/resolv.conf.backup
ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
Stop DNSStubListener:

systemctl reload-or-restart systemd-resolved

Yet /etc/resolv.conf still looks like this and the adguard docker host 10.0.0.8 is NOT being used for DNS as a result

nameserver 8.8.4.4
nameserver 8.8.8.8
# Too many DNS servers configured, the following entries may be ignored.
nameserver 10.0.0.8
search .
