I have a comic strip book in cbr (Calibre?) format. How can I convert it to pdf in my Ubuntu 12.04? I tried to install calibre hoping that it is able to do so. But it seems to be buggy and does not show up. Appreciate your hints to do the conversion.

It's worth pointing out that the CBR (and CBZ) formats are not Calibre specific. They are "Comic Book Rar" and "Comic Book Zip" formats respectively. – Adam Ness May 23 '14 at 15:40

Found a nifty way to do this. Programs that you might need are rar and imagemagick.

sudo apt-get update
sudo apt-get install rar imagemagick

Next, rename all the files extension that you want to convert, from *.cbr to *.rar.

Example: comic.cbr --> comic.rar

Next, use rar and extract all the .rar files. You should get .jpg files as output.

Next, use imagemagick to covert all into one. Make sure you are in that directory.

Example use in terminal:

convert *.jpg comic.pdf

I'm using ubuntu 12.04 and calibre did the job perfectly for me. Your problem is installing calibre. If I'm not wrong I managed to install it by upgrading python

Just found another command line tools that works great

you can install in /usr/bin

I requires some packages that you can install with

sudo apt-get install pdftk sam2p unrar unzip

Then just launch

cbr2pdf [file.cbr]

To have file.pdf on the same directoy
