    If you wish to run apt-get, you will either need to grant a root password,
and use su, or mount the filesystem on some other machine, chroot into it, and
install sudo from the chroot.

    Because the sudo package is not installed, so there is no interpretation
of the sudo group meaning anything.  While the adm group does grant the ability
to access many files, it does not provide for any sort of root access.
