Apt-offline adds offline package management features to Debian-based systems. It may be used to download packages and dependencies that will be installed later (or necessary to update) in a disconnected system. Packages can be downloaded from another connected PC. It may also get bug reports for the downloaded packages. Apt-offline is an Offline APT Package Manager. It can fully update and upgrade an APT-based distribution without connecting to the network, and it does so invisibly to APT. . apt-offline may be used to produce a signature on a system (with no network). This signature provides all download information necessary for the APT database system. This signature file may be used on another system connected to the internet (which does not have to be a Debian box and can even run Windows) to download the updates.

On Ubuntu 20.04, there are three options for installing an apt-offline. Apt-get, apt, and aptitude are all available. Each of the strategies for the installation of this tool will be described in detail in the following sections. You may select any of them.

Example 2: We tell apt-offline that foo.sig is an input to the apt-offline command, not the —install-packages option, by using the — delimiter. Otherwise, you may put it next to the set command.

apt-offline set foo.sig –update –upgrade –install-packages apt
