Audacity 2.3.3 on ubuntu 16.04

I had a working v2.3.1 version of Audacity, on ubuntu 16.04.06 (x64).

The ubuntu software-updater updated it to version v2.3.3 and it now cannot find working ffmpeg library.
Audacity now reports “FFmpeg library not found:”
"Audacity needs the file ‘’ to import and export audio via FFmpeg. Location of ‘’.

Looking for advice on how to fix or workaround the error.

This file is not on my filesystem.

But I do have these libraries: (for Google Earth, and gimp(snap) and also /usr/lib/x86_64-linux-gnu/'

I saw on the documentation page

"“Navigate to the folder that contains FFmpeg and select the file or other appropriate libavformat version.”

I tried to use


for audacity, but the diagnostics > show log has:

I have these ffmpeg packages installed:

ffmpeg-dbg/xenial-updates,xenial-security 7:2.8.17-0ubuntu0.1 amd64

I guess that you must have got that from a PPA.
Look on the web page of that PPA to see if they still offer the 2.3.1 version for download. If they do, then:

  1. Uninstall Audacity
  2. Remove the PPA from your sources
  3. Manually install the 2.3.1 version.

If they don’t offer the 2.3.1 version, then you will either need to revert to the official Ubuntu 16.04 version, or build Audacity from the source code.
To revert to the official Ubuntu version:

  1. Uninstall Audacity
  2. Remove the PPA from your sources
  3. Reload the package list
  4. Install Audacity.
