I don't think that's necessary as "update the package lists" is already very precise. Nor do I think it's a good idea to extend that message to two lines or over 80 characters. And even if, it should say "aptitude update" if it's an error message by aptitude. > If that is indeed what you mean. At least in this case, it won't help as "apt-get update" might error out with a very similar error message, as that's likely the real cause: > W: Could not lock the cache file; this usually means that dpkg or > another apt tool is already installing packages.
