Public bug reported: apt-get update is not fetching packages from external repositories in Xenial. I have a few added in my system, but let's consider the following two as examples: http://ppa.launchpad.net/noobslab/icons/ubuntu This provides a package called ultra-flat-icons, among many others
http://ppa.launchpad.net/mozillateam/firefox-next/ubuntu This provides a package called firefox-next Neither of the above-mentioned packages show up in apt-cache search after an update: ~ » sudo apt-get update Hit:1 http://ppa.launchpad.net/mozillateam/firefox-next/ubuntu xenial InRelease Ign:2 http://repo.vivaldi.com/beta/deb stable InRelease Hit:3 http://ppa.launchpad.net/noobslab/icons/ubuntu xenial InRelease Get:4 http://archive.ubuntu.com/ubuntu xenial InRelease [95.8 kB] Hit:5 http://repo.vivaldi.com/beta/deb stable Release Hit:7 http://archive.canonical.com/ubuntu xenial InRelease Hit:8 https://deb.opera.com/opera-developer stable InRelease Hit:9 http://archive.ubuntu.com/ubuntu xenial-updates InRelease Hit:10 http://archive.ubuntu.com/ubuntu xenial-backports InRelease Hit:11 http://archive.ubuntu.com/ubuntu xenial-security InRelease Get:12 http://archive.ubuntu.com/ubuntu xenial/universe amd64 Packages [7,326 kB] Get:13 http://archive.ubuntu.com/ubuntu xenial/universe i386 Packages [7,307 kB] Get:14 http://archive.ubuntu.com/ubuntu xenial/multiverse amd64 Packages [139 kB] Get:15 http://archive.ubuntu.com/ubuntu xenial/multiverse i386 Packages [136 kB] Fetched 15.0 MB in 25s (600 kB/s) Reading package lists...
