On the disconnected (air-gapped) computer we will firstly determine which pre-installation required packages need to be downloaded:
# First we # We check if tar package is installed:
type tar
tar is /bin/tar
# tar package is installed
# We will only consider downloading and installing it later if we find we are unable to unpack the Opmantek Installer Runfile.
# From the above checks on this disconnected (air-gapped) computer, we have ascertained that no packages are needed.
# Since we don't have any package to download in this example we will download the tar package.
# We will assume for the purposes of this example that the tar package needs to be updated to a newer version.Using the connected computer with same OS and Version we would now fetch the pre-installation required packages:
# Navigate to a clean directory to download packages to
mkdir -p /tmp/omk_opXyz_packages
cd /tmp/omk_opXyz_packages/
# Since we don't have any package to download in this example we will download the tar package.
# We will assume for the purposes of this example that the tar package needs to be updated to a newer version.
# The command to download tar package with dependencies is:
apt-get download tar
Get:1 http://ftp.us.debian.org/debian stretch/main amd64 tar amd64 1.29b-1.1 [759 kB]
Fetched 759 kB in 2s (305 kB/s)
# Downloaded packages will now be in the current directory and ready for transferring to the disconnected (air-gapped) computer where they will be installed:
ls -la-rw-rw-r--. 1 user user 4463036 Apr 3 21:12 759354 Oct 31 2016 tar_1.29b-1.1_amd64.deb
On the disconnected (air-gapped) computer we will now install the downloaded required packages:
# Install each of the downloaded required packages, here using libacl1 as an example, even though it is not actually needed in this case:
sudo apt-get install tar_1.29b-1.1_amd64.deb
