Too long hostnames cause "[ Couldn't determine hostname for lock file: File name too long ]" in nano

[Karl-Philipp Richter]

It'd be nice if `ubiquity` could prevent long hostnames which cause `[ Couldn't determine hostname for lock file: File name too long ]` in `nano` if `sudo nano [path to inexisting file]` is invoked.

I have hidden the previous comment as essentially targeted spam; while it is superficially related to this bug, it is advertising a Windows tool that cannot possibly be relevant here.

File name too long is a common problem. There are various tools for solving this. But I think Long Path Tool will be the best.
