A question about groups

[stan]

I am trying to build an example package from source using the instructions
at:

https://www.cyberciti.biz/faq/rebuilding-ubuntu-debian-linux-binary-package/

When I run the first commaind, I get the following error message:

dpkg-source: info: applying 0203_generic-arch-fallback.patch
W: Download is performed unsandboxed as root as file 'mplayer_1.3.0-8.dsc'
couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission
denied)

Do I need to add the user I am doing this as to a special group?
