I have a daemon running in a chroot jail that I have generated with debootstrap.

I'd like to remove apt and dpkg from the jail, but I want to keep the other packages updated.

Can I upgrade the packages in the jail, running apt-get from outside?

I'm not sure why you want to do this. dpkg and apt are fundamental parts of a Debian system, and your chroot won't function independently without them. Running

chroot /path/to/chroot apt-get update

and so on is a supported method that doesn't require removing dpkg and apt.

But if you're sure you want to do it, you can run

APT_CONFIG=/path/to/apt.conf apt-get update

where /path/to/apt.conf is the path of an apt.conf file that includes

RootDir /path/to/chroot;

The rest of the apt configuration will then be read from /path/to/chroot/etc/apt/apt.conf.d, or somewhere else under /path/to/chroot if you change Dir::Etc in the apt.conf file. See the Description and Directories sections of man apt.conf for details.
