I'm using a Canonical-provided Amazon AMI as a baseline for a new AMI, but when I attempt to install the libsnmp-dev package (which I need in order to have access to net-snmp-config for some reason, even though you certainly don't need to be developing SNMP code in order to want to configure an SNMP user and key), everything blows up with non-existent dependencies.

The AMI is configured with whatever the default repos are in /etc/apt/sources.list. If finds libsnmp-dev without difficulty, but all of its dependencies fail with 404 errors - and looking at the repos in question, they all have packages with the correct name, but different version numbers. I'm new to Ubuntu, and so far pretty much hating it because of this problem. Isn't the whole point of package management systems to avoid these kinds of problems.

  1. What do I need to do to resolve the dependencies?
  2. Why are the official Ubuntu repos serving up versions of packages for which they do not have valid dependencies?

I've wasted the better part of an 8 hour day just trying to install this trivial little command line utility.

    Have you done a sudo apt update recently? – fkraiem Dec 20 '17 at 01:37
  • Also it looks like your DNS could be doing something funny; 34.229.132.181 is not the address of security.ubuntu.com. – fkraiem Dec 20 '17 at 01:41
  • @fkraiem: The Amazon cloud instances by Canonical probably redirect the traffic to repository mirrors inside Amazon's own infrastructure to save cross-network bandwidth. whois 34.229.132.181 is indeed registered to Amazon's cloud computing infrastructure. – David Foerster Dec 20 '17 at 03:40

    I poked around on 34.229.132.181 a.k.a. us-east-1.ec2.archive.ubuntu.com and found that contains very few binary packages for Xenial for whatever reason. That repository "mirror" is practically useless. I don't know if that's intentional or if Canonical is responsible for it, which means I can't tell if this question is on topic. If you're paying money to Canonical for this server instance I recommend that you contact their support for help. – David Foerster Dec 20 '17 at 03:49
  • fkraiem does appear to be on to something, visiting a URL at random from the failures one sees that the file isn't present in the folder (hence the 404) but there is a newer version. Perhaps their manifest is wrong. You could either use your browser or eg sudo apt-get download linux-libc-dev to get the files and then install them with something like sudo dpkg -i ./$FILENAME.deb. – pbhj Dec 23 '17 at 23:31
  • So, here we are a month later, and Canonical have shipped at least one new version of the amazon AMI, since the one I'm using now is dated Feb 05, and this is till not fixed. Top quality support of their own product from Canonical. Of course, the set of broken dependencies is different now, but it still cannot install libsnmp-dev on an amazon EC2 instance running your own ami-0b383171 – Franklin Roosevelt Feb 12 '18 at 20:07
