Bug Description

== Comment: #0 - IRINA YASHINA - 2016-02-18 07:31:18 ==
I tried to install Ubuntu16.04 with preseed file.
When IPv6 address was used in preseed/url:


the error message with wrong url appeared in installer (error scrinshot),
the preseed file couldn't be used.

In the syslog we can see the following messages with incorrectly changed url:

Feb 18 07:33:31 main-menu[501]: DEBUG: resolver (libc6-udeb): package doesn't exist (ignored)
Feb 18 07:33:31 main-menu[501]: INFO: Menu item 'network-preseed' selected

The syslog is attached.

Here are the output of the 'fetch-url' and 'wget' commands in shell:

With IPv4 address in preseed/url no problems were found,
the preseed file was successfully applied in installer.

I've checked the last version of the installer:

The bug still takes place.

I have opened a Debian bug to address this issue. A problem fix is also attached.
