How To Fix gfcombine: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu gfcombine is provided by libgfshare-bin package.

libgfshare-bin is:

This package contains the gfsplit and gfcombine binaries.

gfsplit can be used to split a secret file (like a GPG secret key) into multiple parts, so that at least some number of those parts are needed to recover the original file, but any smaller combination of parts is useless to an attacker. gfcombine is used to combine the parts created by gfsplit.

For instance, you might split a GPG key using a 3-of-5 share and put one share on each of three computers, and two shares on a USB memory stick; then you can use the GPG key on any of those three computers using the memory stick, but if the memory stick is lost, you can recover the key by bringing the three computers together.

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

sudo apt-get -y install libgfshare-bin

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

You can also use apt command to install libgfshare-bin.

sudo apt -y install libgfshare-bin

Or if you have aptitude installed you can use the following command.

sudo aptitude install libgfshare-bin
