You'll need to describe what you tried to do (as specifically as you can.)
The command line:
Code:
sudo python -c "import urllib2; exec urllib2.urlopen('http://status.calibre-ebook.com/linux_installer').read(); main()"
will install it, but you must make sure you have
python 2.6,
glibc 2.10 and
xdg-utils installed first. There may be other dependencies.
The Calibre Linux download page has this information.
I'm not familiar with SUSE; you may need to read up on installing software. If you're a Linux noob, you might want to try Ubuntu instead of SUSE -- it's pretty user-friendly.
