I am new to Linux. In General a couple of days as you get used to. Today tried to install mongodb in this
guide and kind of did, it works.
However, when I do in terminal
sudo apt-get update
get the following error
W: The repository 'http://repo.mongodb.org/apt/ubuntu serena/mongodb-org/Release 3.0' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.

E: Some index files failed to download. They have been ignored, or old ones used instead.
Update Manager in the tray screams 'Could not refresh a list of updates'. When I I press Refresh, it gives me Could not download all repository indexes

What I need to do something to get rid of these messages to the update manager could automatically do refresh?
