RE: broken dist-upgrade
Nonsense. *apt* will only install what it has to in order to upgrade you,
while dselect can and does gift you with a whole new set of software you may
not want, since it obeys things like 'Recommends:' that apt has no reason to
pay any attention to. The *dependency* resolution between them is
identical.
apt-get upgrade will only replace already installed packages.
apt-get dist-upgrade will only replace already installed packages, with the
caveat that if it is necessary to replace an already installed package, it
will allow the installation of a new package.
Example: package_a-1 is installed. There is a new one, package_a-2,
however it has a dependency on package_b that the -1 package did not.
'upgrade' will not install the new package_a, since it is not allowed to use
package_b in its dependency solution. 'dist-upgrade', however, WILL install
the new package_a, and package_b as well.
dselect, on the other hand, will install the new package_a, install
package_b, and a raft of other stuff as well.
"Friends Don't Let Friends Use DSELECT". (should be a bumper sticker)

Redo "apt-get dist-upgrade", it will attempt to restart the unfinished
downloads at the point where they broke off. Repeat until all are
complete.
But really, upgrading your dist should be done with dselect. You can
still do that. Just use "install" from its main menu to perform the
above, after you've checked the select screen.
