- Anything that isn't part of the official public repo(s) is asecond-class citizen. Ex: AFAIK, You can't really do anything like "apt-get install http://example.com/foo/bar-2.7" or "apt-get install./private-package-that-joe-sent-me-via-email".
You can do dpkg -i ./private-package-that-joe-sent-me-via-email".
