Eu experimentei o mesmo problema, e procurar outro espelho resolve esse problema

de /etc/apt/sources.list edite esta parte

http://dell.archive.canonical.com/updates/dists/xenial-dell/InRelease

Substitua "dell.archive.canonical.com" por outro espelho com a mesma finalidade ou pacotes que você precisava, se tiver.
