How To Fix tar2sqfs: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu tar2sqfs is provided by squashfs-tools-ng package.

squashfs-tools-ng is:

SquashFS is a highly compressed read-only filesystem for Linux, optimized for small size and high packing density. It is widely used in embedded systems and bootable live media.

SquashFS supports many different compression formats, such as zstd, xz, zlib or lzo for both data and metadata compression. It has many features expected from popular filesystems, such as extended attributes and support for NFS export.

As the name suggests, this is not the original user space tooling for SquashFS. Here are some of the features that primarily distinguish this package from the original:

• reproducible SquashFS images, i.e. deterministic packing without any local time stamps,
• Linux gen_init_cpio like file listing for micro managing the file system contents, permissions, and ownership without having to replicate the file system (and especially permissions) locally,
• support for SELinux contexts file (see selabel_file(5)) to generate SELinux labels.

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

sudo apt-get -y install squashfs-tools-ng

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

You can also use apt command to install squashfs-tools-ng.

sudo apt -y install squashfs-tools-ng
