Change your repository information to point to different repository mirrors and try again. There are very many to choose from.
Check your internet connection.

It may help to see the list of repositories you are using.
This should show them:

grep ^[^#] /etc/apt/sources.list /etc/apt/sources.list.d/*

or this:

sudo grep -Erh ^deb /etc/apt/sources.list*
