I installed unrar-free, but I cannot extract a multi-file .rar archive (my_archive.part01.rar, my_archive.part02.rar, etc.):

$ ls
my_archive.part01.rar
my_archive.part02.rar
my_archive.part03.rar
$ unrar -x my_archive.part01.rar

unrar 0.0.1  Copyright (C) 2004  Ben Asselstine, Jeroen Dekkers


Extracting from /home/morgan/my_archive.part01.rar

Extracting  my_text_file.txt      Failed
1 Failed

I have read that I need unrar-nonfree to manage multipart archives, but It seems it is not included in the official Raspbian repo.

How can I install unrar-nonfree?

  1. Uninstall unrar-free.

    $ sudo apt-get remove unrar-free

  2. Make sure you have a source repository by editing /etc/apt/sources.list.

    $ cat /etc/apt/sources.list
# Default repository
deb http://archive.raspbian.org/raspbian wheezy main contrib non-free rpi
# Source repository to add
deb-src http://archive.raspbian.org/raspbian wheezy main contrib non-free rpi

  3. Sync the apt database.

    $ sudo apt-get update

  4. Create a working directory and move into it. The unrar-nonfree command will be built in this directory.

    $ cd $(mktemp -d)

  5. Install the dependencies required by unrar-nonfree.

    $ sudo apt-get build-dep unrar-nonfree

  6. Download the unrar-nonfree sources and build the .deb package.

    $ sudo apt-get source -b unrar-nonfree

  7. Install the generated .deb package. Its name varies depending on the version of unrar-nonfree.

    $ sudo dpkg -i unrar*.deb

  8. The working directory you have created in step 4 will be removed at next boot; there is no use to delete it.

Once installed, you can use either unrar or unrar-nonfree (unrar is a simlink to unrar-nonfree).

Warning: unrar-nonfree and unrar-free options are different. For instance, to extract an archive:

$ # with unrar-free
$ unrar -x my_archive.part01.rar

$ # with unrar-nonfree
$ unrar e my_archive.part01.rar

Please man unrar-nonfree for more details.

unrar-nonfree can be installed from Debian armhf repository (it's simply called unrar there). For example, in Raspbian Buster you can run:

wget -qO - https://ftp-master.debian.org/keys/archive-key-10.asc | sudo apt-key add -
echo deb http://deb.debian.org/debian buster main contrib non-free | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get install unrar

Don't forget to disable the Debian repository once you're done: it's not recommended to upgrade your system while having a Debian repository as a source.

An alternative is to install 7-zip with RAR support (though it may not work on newer or password-protected archives):

sudo apt install p7zip-full
