I'm sorry to ask this, but all of the questions along similar lines I could find have been answered by installing unrar/7zip.

So, I received a book in the form of a .rar archive of jpegs. Initially, I tried to uncompress with 7zip from terminal. It goes through each file in the archive and for each file in the archive, says,

Extracting   cover.jpg     Unsupported Method

After doing some quick googling, I thought it was due to lack of .rar codecs, as it's not technically freeware or somesuch. After installing unrar, from the terminal I run

unrar -x Books.rar

And it goes through and just says "Failed" in the place of 7zip's "Unsupported Method."

I thought it could be a corrupt file or something, so I had a friend compress a random jpg as .rar and send it to me, and I encountered the same program. Double clicking it opens unroller, which then promptly closes.

Any help would be much appreciated.

  • Hmm, very strange. I've never encountered any problems using unrar. – user300458 Mar 5 '15 at 5:09
  • I have the same problem. Archive Manager is openning just for a second, and terminal output says failed. – maria Jul 4 '15 at 15:37

Execute following command in terminal :

sudo apt-get install unace unrar zip unzip p7zip-full p7zip-rar sharutils rar uudeview mpack arj cabextract file-roller

Then extract any rar file.

Edit : rar is provided in the multiverse component, so you must enable that repository.

  • many of those are reporting "no installation candidate" -- did you forget to add a PPA? – jcollum Apr 9 '16 at 1:48

    Then you should update your answer to include that – jcollum Apr 11 '16 at 20:19
  • worked! how annoying that there's one 'unrar' that works and another that doesn't. – Amichai Schreiber Nov 25 '16 at 11:41

Complement your installation of 7zip with p7zip-rar, the non-free rar module for p7zip:

sudo apt-get install p7zip-rar
