Unable to point apt sources to Nexus 3.9 with APT plugin about nexus-repository-apt HOT 4 CLOSED

Looks like your repo URL is slightly wrong (missing a "repository" path component). If you go to the repository list page in nexus admin, and use the "Copy" button in the "URL" column that will show you the right URL to use.

Ok!!! I've made progress. Thanks for the tip mpoindexter, but the situation is more complicated than just that. To some what I'm about to detail may seem obvious. Well its not if you haven't spent days trying to understand the Ubuntu repo url scheme and what apt does under the hood. I suggest you include at least a paragraph in the project's doc on the client setup.

After following the project README (https://github.com/sonatype-nexus-community/nexus-repository-apt) and successfully starting Nexus with the APT plug in, here's what I did to make a 100% proxy repo work:

1. Login to Nexus as admin and create a new APT repo.
2. Set the remote storage to a URL from your initial target client's /etc/apt/sources.list. e.g. http://us.archive.ubuntu.com/ubuntu/
3. Set the distribution to your target ubuntu version. Hint you can check which versions accessible by just browsing to the remote storage URL under dists (e.g. http://us.archive.ubuntu.com/ubuntu/dists/). Note that I'm not sure if this is necessary or what it does, but I did it. e.g. xenial or trusty, etc...
4. Get your new Nexus APT repo URL from the "COPY" button in the Nexus admin repo list. e.g. http://192.168.56.101:8081/repository/apt-ubuntu16.04/
5. On the target Ubuntu client, complete the following:
   sudo cp /etc/apt/sources.list /etc/apt/sources.list.bk
   sudo vi /etc/apt/sources.list

Add the following (swap your repo URL links in there):

deb http://192.168.56.101:8081/repository/apt-ubuntu16.04 xenial main
deb http://192.168.56.101:8081/repository/apt-ubuntu16.04 xenial restricted
deb http://192.168.56.101:8081/repository/apt-ubuntu16.04 xenial universe

Note that you need the -updates variants otherwise you'll have broken dependencies when you try to install a newer package. Hint, everything is newer after the 1st Ubuntu distro release.

I have an outstanding question. Do I have to have a separate APT repo in Nexus for each Ubuntu version? e.g. xenial, trusty, etc...? The remote storage URL is not distro specific, and apt knows its distro. I don't think its necessary and means we have to create separate reports for each version, unlike the YUM repo in Nexus which you can just create once. Maybe there's some technical detail that makes this impossible.

@mckenziec - You do currently have to have a separate repo per Ubuntu version.

There's an open ticket to change it (#22), but no one has done it yet. That ticket discusses some of the reasons why, but the short of it is that when I initially wrote this I limited it to one repo per version for no good reason other than it made a couple of things in the code simpler and I had no use cases to do otherwise :)

Closing this out as it appears to be resolved.
