This is a well known issue. If you install haveged: `apt-get install
haveged`
it will improve greatly the time of key generation.
What is entropy and why it is slow? This is beyond my understanding.

After importing your key, you also need to sign it as "ultimately trusted",
which is a geeky way of telling gpg that this is your personal key. This
can be done with `gpg --edit-key` and then either `sign` or `trust` (try
each of them).
