Whenever I do

sudo apt-get update

I get the following error

W: Failed to fetch http://repo.mongodb.org/apt/ubuntu/dists/rebecca/mongodb-org/3.0/multiverse/binary-amd64/Packages 404 Not Found

W: Failed to fetch http://repo.mongodb.org/apt/ubuntu/dists/rebecca/mongodb-org/3.0/multiverse/binary-i386/Packages 404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

How do I solve this issue?

    Did it used to work? mongodb.org currently only has Ubuntu packages for trusty and precise. As docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu says, "MongoDB only provides packages for long-term support Ubuntu releases. Currently, this means 12.04 LTS (Precise Pangolin) and 14.04 LTS (Trusty Tahr)." Commented Jun 1, 2015 at 16:47

Most possible, it means that the repository does not exist anymore.

I have Russian version of Linux Mint, so, excuse me, maybe I will write not exact names below. But I try to translate.

You can go to Update Manager (rus. "Менеджер обновлений"). Just click on pictogram with "i" on bottom panel.

Then choose menu "Edit" -- "Sources of applications" (rus. "Источники приложений") and find here your wrong repository.
You can off it here and error message will disappear.
