I was following some instructions on a website, and it told me to
run sshkeys-lint to check ssh keys.
I never heard of sshkeys-lint and can't
apt-get. Is this a typo?
Wel the question was closed, now that it is open. The link to the article will be extremely useful, but a quick google search shows sshkeys-lint as a utility provided with gitolite
You should be able to install gitolite either by source or via apt-get
