If I accidentally try to install a package with a preinst or postrm
script, it fails as documented at
http://www.maemo.org/platform/docs/howtos/howto_making_an_application_package.html,
with an error message about not being able to chroot to
/var/lib/install.
My question is: having done this, how can I recover back to a sane
state, where I can fix the package and then try installing it again?
Nothing that I can think of works, as shown by the transcript appended
below.
Many thanks,
Neil
