A novel is considered apt when it has a compelling plot that keeps the readers engaged. Good character development and a unique writing style also contribute to its aptness.
I'm not sure specifically what the 'apt 407 true story' is without more context. It could be a story related to an apartment numbered 407, perhaps something that happened there like a mystery, a personal experience, or an event in the building.

Corrupted repositories can be a cause. If the sources.list file (which lists the repositories from where apt fetches packages) is incorrect or if the repositories themselves are corrupted. This can happen due to network issues during an update or if the repository server has some problems. When apt tries to access these bad repositories, it can lead to all sorts of errors and horror - like situations. Another cause could be disk errors. If there are problems with the disk where the apt cache or the package files are stored, it can result in data corruption and apt failures.
One first apt story could be about a young couple moving into their first apartment. They were so excited to have their own place. They spent the whole day unpacking and arranging furniture. By the end of the day, they realized they had no food in the house but were too tired to go out, so they ordered pizza and ate it on the floor, enjoying their new home despite the chaos.
