I am using kubuntu 14.04.2

I have updates set to download and update automatically for where there are security updates - yet the security update for Adobe Flash was not automatically installed when I look a day or two after its release. I had to manually install through the software updater.

It seems it isn't doing what is says it does "Download and install automatically"

I can live with other updates asking for permission - but not security updates.

  • Which package did you install flashplugin-installer or adobe-flashplugin? – Pilot6 Aug 3 '15 at 13:50
  • I have flashplugin-installer installed. Though this may have been after I found that adobe had a serious security flaw and updated it. I'll have to keep an eye on it. Hopefully all is well now. – USER874897 Aug 3 '15 at 18:45

flashplugin-installer package is in trusty-security section of repositories and it should be automatically installed.

But adobe-flashplugin package is not. It is in partner repository.

If you install flashplugin-installer, that should fix this issue.

You can also set up the system to automatically upgrade packages from other sections of Ubuntu repositories.

This setting is in /etc/apt/apt.conf.d/50-unattended-upgrades

If you already clicked to "Download and install automatically" in GUI there must be an uncommented line

"${distro_id}:${distro_codename}-security";

If you uncomment the next line

//  "${distro_id}:${distro_codename}-updates";

by removing //, all updates should be downloaded and installed automatically.

There are also other settings in this file, that are well commented right there.

  • Could you propose a way in which this user could enable automatic updates for Flash? For instance an update script which could be run at intervals or at startup and perform this action. – user364819 Aug 3 '15 at 11:48
  • I feel like this answer is factually incorrect (but currently lack the technical expertise to prove it outright). flashplugin-installer exists in trusty/multiverse, trusty-updates/multiverse and trusty-updates/multiverse. I would think the repo —not the section— would determine which updates are counted as security updates. Chrome is in its own repo, which is why its updates aren't automatically counted as security updates. – Oli Aug 3 '15 at 12:35
  • @Oli Why downvote, if you do not have "technical expertise"? I updated the answer with more details. – Pilot6 Aug 3 '15 at 13:44
  • @Oli But you are correct that flashplugin is in trusty-security. – Pilot6 Aug 3 '15 at 13:48
