Buenos días comunidad. Estoy presentando algunos problemas a la hora de utilizar mis repositorios locales de Ubuntu 16.04. Descargue los repos para 32 y 64 bits con apt-mirror llegando a los 145.0 Gb. Mi mirror.list se ve asi:

############# config ##################
#
# set base_path /var/spool/apt-mirror
#
# set mirror_path $base_path/mirror
# set skel_path $base_path/skel
# set var_path $base_path/var
# set cleanscript $var_path/clean.sh
# set defaultarch
# set postmirror_script $var_path/postmirror.sh
# set run_postmirror 0

set cleanscript $var_path/clean.sh
set mirror_path /media/syn/Almacen/Tools/RepoUbuntu/
set nthreads 10
set _tilde 0
set _autoclean 1

#
############# end config ##############

# repos de la UCI 16.04 – 32 bits

deb-amd64 http://ubuntu.uci.cu/ubuntu xenial-proposed main restricted universe multiverse
deb-amd64 http://ubuntu.uci.cu/ubuntu xenial-backports main restricted universe multiverse

clean http://ubuntu.uci.cu/ubuntu

Ahora, luego de descargados los repos modifico el sources.list para apuntar a dichos repos y utilizarlos. Mi sources list luce asi:

deb file:/media/syn/Almacen/Tools/RepoUbuntu/ubuntu.uci.cu/ubuntu xenial main restricted universe multiverse
deb file:/media/syn/Almacen/Tools/RepoUbuntu/ubuntu.uci.cu/ubuntu xenial-security main restricted universe multiverse
deb file:/media/syn/Almacen/Tools/RepoUbuntu/ubuntu.uci.cu/ubuntu xenial-updates main restricted universe multiverse
deb file:/media/syn/Almacen/Tools/RepoUbuntu/ubuntu.uci.cu/ubuntu xenial-proposed main restricted universe multiverse
deb file:/media/syn/Almacen/Tools/RepoUbuntu/ubuntu.uci.cu/ubuntu xenial-backports main restricted universe multiverse

El problema esta entonces a la hora de hacer el update. Una vez que ejecuto el apt-get update, o aptitude update, recibo el mismo error que les muestro:

Son demasiados Hash Sum mismatch, y no puedo acceder a los paquetes del repo para instalar nada. Alguien sabe que puede ser eso ? Saludos y gracias de antemano.
