How To Fix debdelta-upgrade: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu debdelta-upgrade is provided by debdelta package.

debdelta is:

debdelta is a program suite designed to compute changes between Debian packages. These changes (deltas) are similar to the output of the “diff” program in that they may be used to store and transmit only the changes between Debian packages.

This suite contains ‘debdelta-upgrade’, that downloads deltas and use them to create all Debian packages needed for an ‘apt-get upgrade’. It may be used in a Debian/unstable host (to speed up download of new packages), or in a Debian/stable host (for security updates).

Similarly, when this package is installed, the ‘cupt’ package manager will use deltas to upgrade the host.

To fix this problem, we can install more using the command below.

sudo apt-get -y install debdelta

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install debdelta.

sudo apt -y install debdelta
