I'm having trouble installing
It's required for Calibre to convert CBR files.
Anyone an idea on where to get it (package or source)?
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
My PPA contains a libunrar package, if you don't feel like messing around with a manual install.
(or just libunrar :
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
