6.3.7 What to do if the
dpkg command is broken
dpkg may make it impossible to install any
.deb files. A procedure like the following will help you recover
from this situation. (In the first line, you can replace "links"
with your favorite browser command.)
$ links https://http.us.debian.org/debian/pool/main/d/dpkg/
... download the good dpkg_version_arch.deb
# ar x dpkg_version_arch.deb
# mv data.tar.gz /data.tar.gz
# cd /
# tar xzfv data.tar.gz
For i386, https://packages.debian.org/dpkg may also be
used as the URL.
