[Bug 1817358] Re: Ubuntu 16.04 netboot installation failed during loading of installer component libc6-udeb

[Patel]

Hello

what a hideous bug.

Seen with KVM on Ubuntu 18.04, trying with this URL:
http://ubuntu.mirrors.ovh.net/ftp.ubuntu.com/ubuntu/dists/xenial/main/installer-amd64

solved with this URL:

http://ubuntu.mirrors.ovh.net/ftp.ubuntu.com/ubuntu/dists/xenial-
updates/main/installer-amd64

the real bug is in KVM that should provide tested URLs for main distros
(even the Ubuntu distros :)) rather than vaguely handwawing toward the
man page and letting unsuspecting users falling in traps like this one.

this bug should be closed however, it is irrelevant now.
