LibreOffice build dependencies souce URI for Ubuntu (latest) ?

[Cor Nouws]

Hi,

Following this
  https://wiki.documentfoundation.org/Development/Linux_Build_Dependencies

with #2, adding
  deb-src http://archive.ubuntu.com/ubuntu/ distroname main
to /apt/etc/sources.list

then apt-get update gives an error
Err:7 http://archive.ubuntu.com/ubuntu distroname Release

  404  Not Found [IP: 2001:67c:1360:8001::21 80]

And without that line (obviously)
  sudo apt-get build-dep libreoffice
reports the missing source URI..

Asking here since obviously I can't find how the " .. should look
something like these:" from our wiki should be precisely.

Thanks!
Cor
