Cannot apt-get upgrade if squid-deb-proxy-avahi is running

[Ben Rousch]

Binary package hint: squid-deb-proxy

I have a new Ubuntu 10.04 server install and installed squid-deb-proxy avahi-utils and squid-deb-proxy-client . There are no other squid-deb-proxy servers on the network. When I try to apt-get update I get errors like:

W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/lucid-security/multiverse/source/Sources.gz Something wicked happened resolving 'fe80::20c:29ff:fe4d:1bdd:8000' (-9 - Address family for hostname not supported)

 If I stop the squid-deb-proxy-avahi service, I am able to update normally.

Thanks for your bugreport.

It looks like its trying ipv6 for you first and your DNS is not supporting that - did you setup anything ipv6 releated manually?

[Launchpad Janitor (janitor)]

This bug was fixed in the package squid-deb-proxy - 0.3.2

I didn't do anything IPv6. I was using a new, stock install of the
server, so it was using whatever the defaults are.

Thanks for your quick reply Ben,

what is the output of
avahi-browse -kprt _apt_proxy._tcp |grep '^=;.*;IPv4;.*'

on the affected system?

[Ben Rousch (brousch)]

I'm afraid the system no longer exists. It was a virtual machine to be
used at a 10.10 installfest.

I tried to recreate the system, but the recreation does not exhibit this bug.

On my system, this is the output:
=;eth0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local;desktop.local;192.168.1.34;8000;

[Johan van Dijk (johanvandijk)]

And I forgot to add that the error doesn't happen every time.
When it happens, I can "sudo apt-get update" again, and most of the time the error doesn't occur.

[Johan van Dijk (johanvandijk)]

The error happened again.
The output of avahi-browse -kprt _apt_proxy._tcp |grep '^=;.*;IPv4;.*' is:

johan@munin-test:~$ avahi-browse -kprt _apt_proxy._tcp |grep '^=;.*;IPv4;.*'
=;eth0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local;desktop.local;fe80::21b:21ff:fe04:b87a;8000;

When I try it a minute later:
johan@munin-test:~$ avahi-browse -kprt _apt_proxy._tcp |grep '^=;.*;IPv4;.*'
=;eth0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local;desktop.local;192.168.1.34;8000;

In the meantime, I did not change anything to any of the involved computers.

Again, a few minutes later:
johan@munin-test:~$ avahi-browse -kprt _apt_proxy._tcp
+;eth0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local
=;eth0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local;desktop.local;192.168.1.34;8000;
johan@munin-test:~$ avahi-browse -kprt _apt_proxy._tcp
+;eth0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local
=;eth0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local;desktop.local;fe80::21b:21ff:fe04:b87a;8000;

[Johan van Dijk (johanvandijk)]

On a different computer I ran this:

I'm running into this bug also. I haven't done any ipv6 configuration of any kind, but I sometimes run into apt failing because of this error.

Running the avahi-browse command line listed above multiple times in a row with maybe a second or two between each run resulted in the following output--

jesse@wopr:~$ avahi-browse -kprt _apt_proxy._tcp |grep '^=;.*;IPv4;.*'
=;wlan0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local;box.local;192.168.1.10;8000;
jesse@wopr:~$ avahi-browse -kprt _apt_proxy._tcp |grep '^=;.*;IPv4;.*'
=;wlan0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local;box.local;fe80::230:1bff:feb9:1d93;8000;
jesse@wopr:~$ avahi-browse -kprt _apt_proxy._tcp |grep '^=;.*;IPv4;.*'
=;wlan0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local;box.local;fe80::230:1bff:feb9:1d93;8000;
jesse@wopr:~$ avahi-browse -kprt _apt_proxy._tcp |grep '^=;.*;IPv4;.*'
=;wlan0;IPv4;Squid\032deb\032proxy;_apt_proxy._tcp;local;box.local;fe80::230:1bff:feb9:1d93;8000;

After writing up the previous part of this comment, I tried running the command line again, and the first result returned a ipv4 result and all of the following requests returned ipv6 results, as above.

[Johan van Dijk (johanvandijk)]

A workaround that has worked every time so far: restart the squid-deb-proxy-avahi process on the server machine.
sudo service squid-deb-proxy-avahi restart

The problem seems to occur when the server is on for a couple of days or a week. The first few days everything works without problems.

Status changed to 'Confirmed' because the bug affects multiple users.
