   hdmi_group=2
   hdmi_mode=48
   hdmi_drive=2
   config_hdmi_boost=4
   start_x=0
   gpu_mem=8
   dtparam=spi=off
   dtparam=i2c_arm=off
   max_usb_current=1 # maximum current for usb

2. Run raspi-config.

   $ sudo raspi-config

   Please select each option that you interested in to config.

   • Expand Filesystem.
   • Change User Password.
   • Boot Options: B1 Console.

1. Update packages index from official repository.

   $ sudo apt-get update

2. Upgrade installed packages.

   $ apt-get upgrade

1. List installed packages and save it to a file.

   $ dpkg-query --show -f '${Package}\n' > pkgs.list

• Find the Debian and Raspbian archive keyrings on their official repositories respectively.
• Add Debian and Raspbian archive keyrings.

  $ gpg --keyring debian-archive-keyring.gpg --export|gpg --no-default-keyring --keyring trustedkeys.gpg --import
  $ gpg --keyring raspbian.public.key --export|gpg --no-default-keyring --keyring trustedkeys.gpg --import

• List the added keys.

  $ gpg --list-keys --with-colons

• Test the scripts by running them.
• Add crontab.

  $ nano /etc/cron.d/debmirror or /etc/crontab

• Restart crontab service.
