| Subject: | lintian fails if the machine has a link-local IPv6 nameserver configured |
We have the following bug reported to the Debian package of Net-DNS
(https://bugs.debian.org/765327):
It doesn't seem to be a bug in the packaging, so you may want to take
a look. Thanks!
Please note that the Debian bug report contains a proposed patch.

Package: libnet-dns-perl,lintian
Severity: normal
This is likely a bug in libnet-dns-perl but I wonder if there are network
accesses from lintian.
% lintian ./openclonk_5.5.1-1_amd64.changes
warning: Cannot load check "binaries"
unresolvable name: fe80::4ee6:76ff:fe51:ae30%eth0 at /usr/share/perl5/Email/Valid.pm line 41.
Compilation failed in require at /usr/share/perl5/Lintian/Check.pm line 27.
BEGIN failed--compilation aborted at /usr/share/perl5/Lintian/Check.pm line 27.
Compilation failed in require at /usr/share/lintian/checks/binaries.pm line 30.
BEGIN failed--compilation aborted at /usr/share/lintian/checks/binaries.pm line 30.
Compilation failed in require at /usr/share/perl5/Lintian/CheckScript.pm line 253.
This is due to:
% cat /etc/resolv.conf
[...]
nameserver 10.0.3.1
nameserver fe80::4ee6:76ff:fe51:ae30%eth0
[...]
The syntax is perfectly valid and understood by glibc, but apparently
libemail-valid-perl tries to resolve(!?) it and fails. No, it just
loads Net::DNS::Resolver:
$Resolver = Net::DNS::Resolver->new;
So it seems what explodes is Resolver/Base.pm's nameservers sub.
The message lintian displays is rather awkward: for a runtime error (runtime
configuration not parsable) one gets compilation failed. But I guess the load
is already guarded, hence the warning?
