Bug Description

Binary package hint: update-notifier-common

Right now, /etc/motd says this:

15 packages can be updated.
18 updates are security updates.

...which seems to imply that three security updates cannot be installed. Yikes.

The problem is in the /usr/lib/update-notifier/apt-check script: in the section

       if cand_ver != inst_ver:
                # check for security upgrades
                upgrades = upgrades + 1
                if isSecurityUpgrade(cand_ver):
                    security_updates += 1
                # now check for security updates that are masked by a
                # canidate version from another repo (-proposed or -updates)
                for ver in pkg.VersionList:
                    if (inst_ver and apt_pkg.VersionCompare(ver.VerStr, inst_ver.VerStr) <= 0):
                        #print "skipping '%s' " % ver.VerStr
                        continue
                    if isSecurityUpgrade(ver):
                        security_updates += 1
                        break

it is double-counting some security updates. I have a patch which fixes this.

Ack! I flipped the arguments to "diff -u". Please ignore the above patch (although it's simple enough to see what it's supposed to do) and use this one.

This bug was fixed in the package update-notifier - 0.86

---------------
update-notifier (0.86) karmic; urgency=low

  [ Sebastien Bacher ]
  * debian/rules:
    - build using --as-needed to reduce the depends

  [ Dustin Kirkland ]
  * debian/update-notifier-common.dirs: update-notifier-common
    needs /etc/update-motd.d, rather than /etc/update-motd.d/hourly;
    causes this directory to *not* be removed on update-motd package
    removal/upgrade

  [ Michael Vogt ]
  * src/update-notifier.c:
    - if display can not be opened, show a propper error message
      and do not crash (LP: #317745)
  * src/apt_check.py:
    - count security updates correctly even when they are "shadowed"
      by a regular update (LP: #394958)
    - fix typo (thanks to Hew McLachlan)
  * data/update-motd-updates-available, debian/99update-notifier:
    - move updates available from /var/run to /var/lib/update-notifier
      to make it persistent over reboots
  * src/update-notifier.c:
    - make the timeout for no-activity from apt bigger (LP: #274001)
  * data/update-notifier.desktop.in:
    - better description for the auto startup (LP: #146918)
  * src/update-notifier.c:
    - use GAppInfo/GAppLaunchContext to provide startup notification
      support (LP: #46258)
