Comment # 13 on bug 492261 from Eberhard K�mmerle

For those, who want an immediate solution and accept the risks described by 
Michael Andres:

I wrote the following script 'zypper-ignore-errors' that calls zypper in
interactive mode and provides the needed answers automatically:

##################
#!/usr/bin/perl

use Expect;  # needs package 'perl-Expect'
use strict;

my $exp = Expect->spawn('zypper', @ARGV);
while ($exp->expect(36000,
    [ qr|Abort, retry, ignore\? \[a/r/i.*\):|,                     sub
{$exp->send("i\n");}],
    [ qr|Do you want to disable the repository .* permanently\?|,  sub
{$exp->send("no\n");}],
    [ qr|\? \[.*\):|,                                              sub
{$exp->send("\n");}]
)) {}
##################

You can call it like that (important: WITHOUT --non-interactive):
zypper-ignore-errors --quiet up -t patch --auto-agree-with-licenses

Best regards,
  Eberhard
