How can I add an unlisted repository to my Software Sources via its (http/ftp)://... URL?
I am not referring to a single entry in the /etc/apt/sources.list.
The URL I am referring to points to a full-and-complete repository (security updates main restricted universe mutliverse).
I know about manually editing
/etc/apt/sources.list, but that is a general pain compared to just adding the repository's URL into Software Sources (if it is possible).
Is the Software Sources server-list dynamically downloaded from Canonical, and/or is it somewhere on my file-system? ... and would it work if I just add my URL to this list, and then choose it via the normal Software Sourced dialog?
There doesn't seem to be an "Add" option in the "Ubuntu Software" tab of Software Sorces. I can only find the "Other" option, which allows me to choose an alread listed server.
I've just found a tool called
apt-mirror which allows the building of a local mirror, so I assume that there must be a way to use this new mirror, and that it grafts into the normal apt-get/aptitude/Synaptic system.. My "new" mirror is my ISP's not-fully-public Linux mirror, and I assume it can be grafted in, too.. Am I on the right train with this line of thought?
