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)?
My PPA contains a libunrar package, if you don't feel like messing around with a manual install.
sudo apt-add-repository ppa:bodiltv/ppa
sudo apt-get update
sudo apt-get install calibre
(or just libunrar :
sudo apt-get install libunrar)
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
Since Ubuntu 19.10 it is packaged in the repositories as libunrar5:
sudo apt install libunrar5
It will install the library as
/usr/lib/x86_64-linux-gnu/libunrar.so.5, assuming a 64-bit Ubuntu. Since 20.04 there's no 32-bit (i386) version on repositories.
You could also download UnRAR source directly from the official RARLab website and easily build
unrarlib.so from source:
tar -xf 'unrarsrc-5.9.4.tar.gz'
That will produce
unrarlib.so in the newly created
unrar directory. Now just move/copy/symlink it to
/usr/local/lib and you're good to go!
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
