netinstall refuses to use local mirror

Bug Description

I am in charge of Ubuntu deployments at our organization, and in the past we have used kickstart + preseed files to deploy a tested, customized Ubuntu workstation. Although we do not have a huge number of Ubuntu users, I perform a substantial amount of testing on a configuration prior to mass deployment. Because of this all this testing, I have found that using apt-mirror to create a local mirror of packages saves me an enormous amount of time and bandwidth. This setup worked with both jaunty and lucid. However, with maverick, copying and updating the kickstart and preseed files does not work as before. While the system configuration settings from the kickstart seem to be followed correctly, the installer completely ignores the local mirror configuration and downloads every package from the Internet.

Hi Rafael,

Thank you for your response. However, it appears I may not have made myself clear. My organization is trying to deploy Ubuntu using an internal mirror of the Ubuntu repositories. We do NOT want to connect to the Internet at all during a kickstart installation. Even if I replace all instances of references to external Internet mirrors with our own private mirror, the installer still insists upon accessing the Internet, thus drastically slowing down the installation process.

I believe I have the same issue.
We have been deploying Ubuntu by pointing the Ubuntu mirror to an internal mirror with a preseed file. This has been working for us since Ubuntu 7.04. I use the same preseed file and just change the directory. Now it's trying to install from The d-i installer stops with the error:
Bad archive mirror. An error has been detected while trying to use the specified Ubuntu archive mirror.

my preseed file mirror section:
d-i mirror/country string manual
d-i mirror/http/hostname string {our internal http server}
d-i mirror/http/directory string /ubuntu/1010-64
d-i mirror/suite string maverick
d-i mirror/http/proxy string

i have the exact same issue.
As a workaround i added two entries

d-i mirror/country string enter information manually
>> d-i mirror/http/countries string enter information manually
d-i mirror/http/hostname string
>> d-i mirror/http/mirror string
d-i mirror/http/directory string /ubuntu
d-i mirror/suite string natty
d-i mirror/http/proxy string

This seems to work but it's not a nice clean solution :)

I use the following settings. The local server isn't used. Affects 12.04

d-i mirror/protocol string http
d-i mirror/country string manual de
d-i mirror/suite string precise
d-i mirror/http/hostname string
d-i mirror/http/mirror string
d-i mirror/http/directory string /ubuntu/
d-i mirror/http/proxy string

I ran into the following today too. Looking at the debian installer source ( it looks like support for the "enter information manually" strings have been removed in favour of "manual" . So the example from William at response #8 should be:

d-i mirror/country string manual
d-i mirror/http/countries string manual
d-i mirror/http/hostname string
d-i mirror/http/mirror string
d-i mirror/http/directory string /ubuntu
d-i mirror/suite string natty
d-i mirror/http/proxy string

And Christian Orth (#9) would not work because the string should be "manual" and not "manual de".

I am attaching the contents of "git show bb1bdcaa4eecfc47b69420c0687eb3c2bc8e1d01" from the source. The changelog message was: 'Drop backwards compatibility for preseeding "manual" mirror selection. Change was introduced in Lenny.
One release is enough for backwards compatibility support.'

I am guessing that there is a lot of documentation out there that needs to be changed now.
