Hi, the Rasp Pi don't have the "rar" command to pack RAR archives on Mystic.
I can't find one valid package to install it. I only see "unrar", that i already have. The idea is to update "file_id.diz" on .rar archives.
Thanks.

rar is nonfree and the author is quite unfriendly to open source. it seems they offer a prebuilt linux version that's not free either, but is only x64

I thought I'd find a good answer on this, because I thought it'd just be sudo apt-get install rar, but evidently, since rar is proprietary software, it's not available in Raspbian or Debian ARM.

(Or at least wasn't 13 years ago)

And, yeah, I'm not seeing any particularly-easy solution for you.

Well, other than converting all .rar files to a different format. Which may not count as "particularly easy".

Hopefully someone else has something more useful to say.

Interesting.. I've been using Intel x86/64 compatible Linux distros for years, and there is a rar and unrar I've been able to install and use for free on those. I currently have rar and unrar for Linux installed on my Linux Mint 22.3 and KUbuntu 26.04 systems at home.

RAR compression algorithm is not open source, so no free util to compress files... I must use a different archive format.

Hi fusion,

You are right,

"The non reverse engineering clause about the RAR compression algorithm and code apply as well for any rewritten version, so no Free Software, royalty free RAR archiver and compressor can be created under current licensing terms. In other words, no open source alternative exist to WinRar's Rar.exe

7z (7-zip) supports extracting RAR files.. Does 7z not support compressing RAR as well?

I believe I use 7zip here for just about everything it can handle.

sudo apt install rar, then unrar worked for me with Linux Mint.

No, only extracting RAR files.

This apt install don't work, no package candidate. But with "unrar" is OK
but this is not what i'm looking for.

Okay, so unrar is available royalty free, but that doesn't explain why rar (the compressor) is available free on Linux?

It install on my Linux Mint(!), with "apt install rar" and i got this:

I don't know the limitations of the trial version.

Try this?

https://www.win-rar.com/rar-linux-mac.html?&L=0

Click on the "Download" tab at the bottom, and scroll down to the Linux version. It may just be a binary, and it's definitely command line only from what it says on that page.
