What is osmoma/audio-recorder/ ?

[GregM]

Every time I do $ sudo apt-get update && sudo apt-get dist-upgrade 16.04 tries to update osmoma/audio-recorder/
I've looked and can't find it on my computer.
I've tried to remove it and it says it isn't there.
I've tried to purge it and it says it isn't there.

What's going on?
How do I stop this?

Remove the PPA.

It seems that the xenial dist has been removed from the PPA:
http://ppa.launchpad.net/osmoma/audi...r/ubuntu/dists

Like SpecialED says, remove the ppa from your sources list.

[GregM]
