Public bug reported: The package which downloads the flashplugin tar is apparently storing it with incorrect permissions which prevent user "_apt" from reading it (presumably without o+r perms). As a result the update process could not drop root permissions and continue. Or, something like that -- see email below.
I can't think of any reason why a downloaded flashplugin file should not be world-readable. So the script which downloads it should be fixed to avoid this. Here's a sample email root gets after any flash update: /etc/cron.daily/update-notifier-common: Get:1 http://archive.canonical.com/pool/partner/a/adobe-flashplugin/adobe-flashplugin_20161026.1.orig.tar.gz [27.2 MB] Fetched 27.2 MB in 13s (2,037 kB/s) W: Can't drop privileges for downloading as file '/var/lib/update-notifier/package-data-downloads/partial/adobe-flashplugin_20161026.1.orig.tar.gz' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied) flashplugin-installer: processing... flashplugin-installer: downloading http://archive.canonical.com/pool/partner/a/adobe-flashplugin/adobe-flashplugin_20161026.1.orig.tar.gz Installing from local file /var/lib/update-notifier/package-data-downloads/partial/adobe-flashplugin_20161026.1.orig.tar.gz Flash Plugin installed.
