preseed fails to add custom repos with apt-setup/local0/repository in xenial

[LoOoD]

The sources file is being written incorrectly during the preseed process. Its failing to prefix the last line in the sources.list file with "deb ".

This is what we have in our preseed for xenial

# Aptly Mirror / Custom Packages
d-i apt-setup/local0/repository string deb http://aptly.internal/internal/company/ xenial main
d-i apt-setup/local0/source boolean false
d-i apt-setup/local0/key string http://aptly.internal/internal/company.gpg
# Aptly Mirror / puppetlabs repos
d-i apt-setup/local1/repository string deb http://aptly.internal/internal/puppetlabs-xenial/ xenial main dependencies
d-i apt-setup/local1/source boolean false
d-i apt-setup/local1/key string http://aptly.internal/internal/company.gpg

I can confirm this bug. Happens to me if I try to preseed install Ubuntu Xenial (with Foreman). The bad news is, that the install fails because apt is unable update (with the error in sources.list) and so no packages for kernel etc. can be found. For me that means I cannot use Xenial at the moment (if I cannot use preseed install it makes no sense on an LTS release).

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

To say it clear once again... This issue disqualifies Ubuntu xenial from professional usage at the moment. Why is this Bug ignored? Could you please at least set an importance Level?

I found a solution that works for me:

By default in xenial documentation:

d-i apt-setup/local0/repository string http://local.server/ubuntu xenial main

But only adding word "deb" before the URL it works:

d-i apt-setup/local0/repository string deb http://local.server/ubuntu xenial main

@Octavi
Well, you found a workaround.
We are using a template based preseed file with the installation managment tool foreman (theforeman.org).
And we have different debian/ubuntu versions in our environment...
I don't wanna script a workaround for every new os version because of new nasty bugs...
A dev involved in this projekt would have fixed it in 10 mins. Maybe the one who broke it even faster ;-)
