Question

[...]                        
Err http://ppa.launchpad.net trusty/main i386 Packages                         
  404  Not Found
[...]
W: Failed to fetch http://ppa.launchpad.net/clicompanion-devs/clicompanion-nightlies/ubuntu/dists/trusty/main/binary-i386/Packages 404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

I've read several forum topics about fixes but there is anyone works.

have you added the PPA yourself? then I suggest checking if the PPA URL is correct — Finlay Roelofs, Sep 01 '15 at 08:27

I've solved it with a bit different way but not as in How can I fix a 404 Error when using a PPA or updating my package lists?. I don't know how to solve it in command line but I did it in UI.

Open update-manager.
After checking go to Settings... > Other Software.
Uncheck all matched with link http://ppa.launchpad.net/clicompanion-devs/clicompanion-nightlies/ubuntu

For now apt-get update works fine.
