[Bug 1624836] Re: ubuntu-bug refuses to file upgrade bug, thinks it's a dupe from 2012

[Brian Murray]

apport checks for a bug pattern before filing a bug report, in the case
of the bug which you were reporting it matched the bug pattern for bug
996916.  That pattern looks like:

    <pattern url="https://launchpad.net/bugs/996916">
        <re key="Package">^(ubuntu-release-upgrader-core |update-manager)</re>
        <re key="VarLogDistupgradeMainlog">blacklist expr '\^postgresql-.*\[0-9\]\\.\[0-9\].*' matches</re>
    </pattern>

>From the bugs I'd seen before most of them failed to calculate the
upgrade, however in your log file (Mainlog.txt) the message appears
during the obsolete package check.

2016-09-18 12:53:10,503 DEBUG Start checking for obsolete pkgs

2016-09-18 12:53:25,980 DEBUG blacklist expr '^postgresql-.*[0-9]\.[0-9].*' matches 'postgresql-9.3'
2016-09-18 12:53:25,980 DEBUG skipping 'postgresql-9.3' (in removalBlacklist)
2016-09-18 12:53:25,980 DEBUG 'postgresql-9.3' scheduled for remove but not safe to remove, skipping

The bug pattern should be modified so that it only matches bugs where
the message appears before upgrading.

Title:
  bug pattern for bug 996916 not specific enough

Status in Apport:
  Triaged

Bug description:
  I wanted to file https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-
  upgrader/+bug/1624835https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1624835 so I ran ubuntu-bug and selected 'ubuntu-release-upgrader'.

  I expected the usual workflow: a magic Launchpad link that makes me
  wait and wait and then eventually lets me file a new bug, which has a
  bunch of relevant information attached to it.

  ubuntu-bug decided instead that my problem was already known, and that
  I should add additional information to this unrelated old bug from
  2012 https://bugs.launchpad.net/ubuntu/+source/update-
  manager/+bug/996916
