Audacity Export Error

I have edited some audio using Audacity, but whenever I try to export the audio to a .mp3 or .ogg file, I get a popup error window saying “An assertion failed!” (see attached picture). Once I get that popup, no matter what I do I am virtually doomed. If I click the x, Audacity crashed. If I click Stop or Continue, Audacity crashes. My computer runs Ubuntu 15.10, and I am using Audacity 2.0.6

Any help would be greatly appreciated.

If your 2.0.6 is the packaged version supplied by Ubuntu, it is an illegitimate version built with a 3.x.x version of wxWidgets that 2.0.6 does not support.

We do still have a problem with that assertion in our current 2.1.2-alpha code which does support wx3.0.2. It’s caused if you click OK on Metadata Editor with one of the value cells open for editing. It sometimes happens if you have just added new content in one of the cells, even if you close the cell by TAB or ENTER. However in 2.1.2-alpha, Continue does not crash.

I would suggest you uninstall your 2.0.6 version and install the 2.1.1 “Ubuntu Handbook” PPA (properly built against wx2.8.12) from The Metadata Editor problem should not occur in that version.


Thanks for your information. I was able to add the Audacity repository and simply update to version 2.1.1 using Synaptic. Thanks once again. Now I shall see whether the problems have been fixed. Even if they are still there, I now know how to avoid them. Thanks for the third time!

The assertion in Metadata Editor is still an open bug in versions of Audacity built with wxWidgets 3.x. You can check Help > About Audacity…, Build Information tab to see what version of wxWidgets your 2.1.1 is built with.
