Version 1.9.6 (changelog) contains many fixes after a security audit.
This release won't work with Pihole on Raspbian Stretch though, right?
Anyone here pls tell me how to update this Unbound to latest version 1.9.6. According to the guide from Unbound installation it sits still at 1.9.0
So is there a simple guide to update or do a fresh installation ? i tried doing it manually but didnt succeed.
Any help is highly appreciated. Thanks
What did you try? Before there are any official builds, you should be able to compile directly from the source code.
git clone https://github.com/NLnetLabs/unbound.git
cd unbound
git checkout release-1.9.6
./configure && make && sudo make install
should be all you need following GitHub - NLnetLabs/unbound: Unbound is a validating, recursive, and caching DNS resolver.
Depending on what is already on your system, you may need to install some building dependencies like
sudo apt install build-essential libssl-dev libexpat1-dev
(this is just an assumption, you may need further packages).
Edit
unbound -V
should now show the 1.9.6 release. After confirming this, run
sudo service unbound restart
to replace the old running unbound
by the newer one. You may want to uninstall unbound
using apt remove
now to avoid your locally compiled variant to be overwritten by updates. If this removes the unbound
binary, simply run the sudo make install
step from above another time.
Hi,
I tried to follow your howto to update unbound on my raspberry.
Installation seams ok, but unbound is unable to start
unbound -v -v -v -v -v -v

How does your configuration look like? The description I gave is only expected to work when unbound
already worked before.
Hi,
Unbound used to work perfectly in version 1.9.0.
config: would say standard, port: 5335
setting IPv6 off does not help.

Where did you get these configuration lines?
Hi,
this was a try an error from my side and recommended in a german forum.
the same error is still here, even if i use the „standard“ config,
GNU nano 3.2 /etc/unbound/unbound.conf.d/pi-hole.conf
server:
# If no logfile is specified, syslog is used
# logfile: "/var/log/unbound/unbound.log"
verbosity: 0
port: 5335
do-ip4: yes
do-udp: yes
do-tcp: yes
# May be set to yes if you have IPv6 connectivity
do-ip6: no
without interface lines
Are there any other files in /etc/unbound/unbound.conf.d
?
Do you have a /etc/unbound/unbound.conf
file?
Check them as well.
Here we go...
GNU nano 3.2 /etc/unbound/unbound.conf
# Unbound configuration file for Debian.
#
# See the unbound.conf(5) man page.
#
# See /usr/share/doc/unbound/examples/unbound.conf for a commented
# reference config file.
#
# The following line includes additional configuration files from the
# /etc/unbound/unbound.conf.d directory.
include: "/etc/unbound/unbound.conf.d/*.conf" ```
root@raspberrypi:~# ls /etc/unbound/unbound.conf.d
localroot.conf qname-minimisation.conf
pi-hole.conf root-auto-trust-anchor-file.conf
root@raspberrypi:~#
What is in the other config files? Something seems to overwrite your
setting somewhere.
/etc/unbound/unbound.conf.d/qname-minimisation.conf
server:
# Send minimum amount of information to upstream servers to enhan$
# privacy. Only sends minimum required labels of the QNAME and se$
# QTYPE to NS when possible.
# See RFC 7816 "DNS Query Name Minimisation to Improve Privacy" f$
# details.
qname-minimisation: yes ```
/etc/unbound/unbound.conf.d/root-auto-trust-anchor-file.conf
server:
# The following line will configure unbound to perform cryptograp$
# DNSSEC validation using the root trust anchor.
auto-trust-anchor-file: "/var/lib/unbound/root.key"
do you think setting up the whole raspberry, pihole and unbound could solve my issue?
is any other user able to run unbound 1.9.6 on a raspberry successfully?
anything else i can try, bevor starting allover with new setup?
Thank you very much supporting me!
Yes, at least I am able to do this but on another Pi on the other end of the country which I cannot access right now.
How do you try to start unbound
? I hope you're using
sudo service unbound restart
and do not try to start it directly as root
. This will not work as it doesn't know which config files to read if you start it manually.
Are you sure there is no port:
setting hidden somewhere ?
