In that last case, you can't even trust apt-get to get the right
package, nor dpkg to install it faithfully. You really have to boot from
trusted media in that case.
The point's taken, nevertheless.
> apt-get install packagename --reinstall
You can also use the tools in the grep-dctrl package in conjunction with
this:
grep-status -FStatus ' installed' | \
grep-dctrl -nsPackage -FEssential yes | \
xargs apt-get --reinstall install
... for instance, to reinstall all essential packages (untested).
Actually the check that the packages are installed is redundant in this
case, but may be useful as an example.
