Dear Maintainer,

When installing grub (here, as the result of a package upgrade), the typical output is something like:

Setting up grub-pc (1.99-27+deb7u3) ...
Installation finished. No error reported.
Generating grub.cfg ...

The use of "error" in "no error reported" triggers regexes in apt-dater used to try and draw attention to issues and errors encoutered upon installing package upgrades.

While it would probably be possible to inverse match on "No error", it would to my mind be preferential to use "success" language rather than "negated failure" language - eg reword to "Installation was successful", or, perhaps, "Installation appeared to be successful".

Thanks for all that you do

Phil
