I am very new to Ubuntu, and am having trouble running an update in order to install the ubuntu-desktop gui. This is a vm server in a production environment, and my end goal is to update my ssl cert on this server.
When i run apt update, I receive the error message :
W: Failed to fetch http://download.owncloud.org/download/repositories/8.2/ubuntu_14.04/packages HttpError404
E: Some index files failed to download. They have been ignored, or old ones used instead.
I have tried to research this, but I cannot find an answer. I believe it has something to do with updating the sources.list file as the error message looks like the download location for the owncloud update has changed. I have no idea what the new location might be, or how to update the sources.list.
I apologize for the long question, but believe once I can get a gui installed, i will be able to navigate this vm much easier.
