libunrar.so not found

I'm having trouble installing libunrar.so. It's required for Calibre to convert CBR files.

Anyone an idea on where to get it (package or source)?

From ubuntu Gert

• download calibre

  http://sourceforge.net/projects/calibre/files/

  select your system :

  64 bits : calibre-x.x.xx-x86_64.tar.bz2

  32 bits : calibre-x.x.xx-i686.tar.bz2

  extract that file and find libunrar.so in the main directory

  copy libunrar.so into "/usr/lib" folder

  Gilles : Put `libunrar.so` in `/usr/local/lib`, not in `/usr/lib`. Never touch anything under `/usr` outside `/usr/local` without going through the package manager. Also, run `sudo ldconfig` after you've installed a `.so` manually.

  hhlp : @Gilles, i think is not necesary execute ldconfig in this case because only use (/lib and /usr/lib) man ldconfig and you are using /usr/local/lib

• you can grab the libunrar.so file from the latest files here http://sourceforge.net/projects/calibre/files/ , make sure to get the right architecture for your system. i got calibre-0.7.23-x86_64.tar.bz2 myself because i have a 64-bit system.

  you can then put that libunrar.so file in /usr/lib and hopefully it should work okay
