Like the OP, I am unable use the generic method (wget) to install Calibre on my Ubuntu 14.04 system due to being behind a proxy server. I've also tried the no-check-certificate method with wget without success.
What I ended up doing was installing Calibre via the repository ("sudo apt-get install calibre") but this version is kind of old. So I figured I'd download the tarball of 2.0 and overwrite the 1.25 version I currently have using the method called out on the download page:
Code:
sudo rm -rf /opt/calibre/* && sudo tar xvf /path/to/downloaded/calibre-tarball.txz -C /opt/calibre
Doesn't work though. Firstly, the repository doesn't install to /opt/calibre. So I did a whereis to find it and found two possible directories:
Code:
$ whereis calibre
calibre: /usr/bin/calibre /usr/lib/calibre /usr/bin/X11/calibre /usr/share/calibre /usr/share/man/man1/calibre.1.gz
I tried:
Code:
sudo rm -rf /usr/share/calibre/* && sudo tar xvf /home/tiffty/calibre-2.0.0-i686.txz -C /usr/share/calibre
and later after reinstalling calibre using apt-get
Code:
sudo rm -rf /usr/lib/calibre/* && sudo tar xvf /home/tiffty/calibre-2.0.0-i686.txz -C /usr/lib/calibre
but in both instances Calibre doesn't start up anymore.
Does the "copy over" technique not work when going from 1.x to 2.0?
