unrar 0.0.1 not working on rar files

[ochieman2000]

Morning,

I have a .rar file needed to be extracted. I installed unrar as I have seen others post is a good one but is not working.

unrar -x [file_name]

gave me this error


Extracting from /opt/minecraft3/Cathedral+of+Azrail+Seal+of+Darkness.rar

unknown archive type, only plain RAR 2.0 supported(normal and solid archives), SFX and Volumes are NOT supported!
All OK



also this is all CLI, do not have a gui
Thanks =)

RAR is not a free format. As the error states, your version of the "free" unrar does not support the way this file was compressed.

RAR - Wiki

Free unrar source code:

int 
IsArchive (void) 
{ 
  if (fread (&markheader, 1, sizeof (markheader), inputfile) != 
      sizeof (markheader)) 
    return 0; 
 
  /* original RAR v2.0 header */ 
  /* FIXME: Endian */ 
  if (!(markheader.head_crc == 0x6152 && markheader.head_type == 0x72 
        && markheader.head_flags == 0x1a21 && markheader.head_size == 0x0007)) 
  { 
    fputs ("unknown archive type, only plain RAR 2.0 supported" 
           "(normal and solid archives), " 
           "SFX and Volumes are NOT supported!\n", stderr); 
 
    return 0; 
  } 
 
  if (ReadHeader (MAIN_HEAD) != SIZEOF_NEWMHD) 
    return 0; 
 
  return 1; 
}

Unrar is at version 4.0.7 at the least, so yours is very much out-of-date. Also, I don't use unrar to extract rar archives, but the rar tool, using the command: rar x 'filename*.rar'
I have been using that for extracting rar archives for years now, with no problems or incompatibilities.

FWIW, RAR may be "proprietary", but there are plenty of reverse-engineered tools out there to archive/extract in this format. The RHEL rar package is at version 3.9.3-4 and unrar at 4.0.7-1. The rar package is in the atrpms repository, and unrar is in the rpmforge repository. Not sure about ubuntu, but I know that I have been able to install the rar package using Synaptic.
