Thanks. > This is likely because the packages come from the ci-train overlay-ppa. This seems to be the case for webbrowser-app but not for apport, and ubuntu-bug still doesn't let me file a bug against apport, in case this helps you understand this issue better. Is this because 2.17.2-0ubuntu1.1 is somehow not in an apt repository from the perspective of "apt-cache policy"? Though "apt-cache show apport" can see it, so I'm not sure what's going on here. phablet@ubuntu-phablet:~$ apt-cache policy apport apport: Installed: 2.17.2-0ubuntu1.1 Candidate: 2.17.2-0ubuntu1.1 Version table: *** 2.17.2-0ubuntu1.1 0 100 /var/lib/dpkg/status 2.17.2-0ubuntu1 0 500 http://ports.ubuntu.com/ubuntu-ports/ vivid/main armhf Packages phablet@ubuntu-phablet:~$ apt-cache policy webbrowser-app webbrowser-app: Installed: 0.23+15.04.20150522.1-0ubuntu1 Candidate: 0.23+15.04.20150522.1-0ubuntu1 Version table: *** 0.23+15.04.20150522.1-0ubuntu1 0 1001 http://ppa.launchpad.net/ci-train-ppa-service/stable-snapshot/ubuntu/ vivid/main armhf Packages 100 /var/lib/dpkg/status 0.23+15.04.20150416-0ubuntu1 0 500 http://ports.ubuntu.com/ubuntu-ports/ vivid/main armhf Packages phablet@ubuntu-phablet:~$ ubuntu-bug apport *** Collecting problem information The collected information can be sent to the developers to improve the application.
