Just quick post for myself. Today I need to give sample to my student about apt-get command and while I try it I got this error :

Err http://ppa.launchpad.net trusty/main amd64 Packages
404 Not Found

Err http://ppa.launchpad.net trusty/main i386 Packages
404 Not Found

W: Failed to fetch http://ppa.launchpad.net/openshot.developers/ppa/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found

W: Failed to fetch http://ppa.launchpad.net/openshot.developers/ppa/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.

Yes. That error mean the address is not found. Might be the address changed or something else.

As I use Peppemint OS 5. I found that source.list is no longer packed in single file but located in directory.

Re run apt-get

$ sudo apt-get update

this time no error message.

How about openshot ?

Well, I try re add the source :

$ sudo add-apt-repository ppa:openshot.developers/ppa
This PPA contains the current stable version of OpenShot Video Editor.

If you would rather the bleeding-edge version, check out the following URL:

Well, I think its openshot repository problem. I skip install this 🙂
