Failure to download extra data files: flashplugin-installer

Today after finishing the update i got update information

I have tried clicking on run action now, but by that nothing happens only terminal opens up and then after minute it automatically closes down.

NOTE:I have seen question related to this, but not sure to use solution as there was pepflashplugin installer while in my case it is only flashplugin installer

Solution 1:

I had the same problem and have fixed it with the following two steps from the command line:

1. Removing flashplugin-installer completely with the following command

   sudo apt-get remove --purge flashplugin-installer
   

2. Re-installing flashplugin-installer again with the command

   sudo apt-get install flashplugin-installer
   

Solution 2:

Another command to force the download to be reattempted:

sudo pkexec /usr/lib/update-notifier/package-data-downloader

I just got this to work in 16.04. This way you don't have to uninstall/reinstall the package. It's the same thing that would happen if you click the "run this action now" button in the GUI.

Solution 3:

Running sudo pkexec /usr/lib/update-notifier/package-data-downloader I received the following error (links obfuscated due to ask policy):

flashplugin-installer: processing...
flashplugin-installer: downloading _http://archive.canonical.com/pool/partner/a/adobe-flashplugin/adobe-flashplugin_20161213.1.orig.tar.gz

E: Download Failed

I manually downloaded the file from the URL specified, created a new 'partial' directory in /var/lib/update-notifier/package-data-downloads, moved the download to there and then ran the sudo pkexec /usr/lib/update-notifier/package-data-downloader command again. Which I think appeared to work (Ubuntu 16.04)

Solution 4:

I had the same problem, and instead of fixing it with the GUI, I simply did sudo apt-get remove flashplugin-installer and sudo apt-get install flashplugin-installer from Terminal. The problem was that my internet connection was unstable, but after doing this a couple times I got the entire file downloaded and installed.

Solution 5:

Per RNA's advice in another post:

sudo rm /var/lib/update-notifier/user.d/data-downloads-failed

fixed on 14.04.

I removed this file in 12.04 LTS, no more error message on bootup, videos play just fine!

Correction: next day error message came back, tried the purge method and re-installed flashplugin, error message appeared immediately.
