After:

wget ftp://ftp.ubuntu.com/ubuntu/pool/main/g/gcj-4.7/libgcj-doc_4.7.2-1ubuntu1_all.deb

(requires gcj-4.7-base)

wget ftp://ftp.na.kde.org/pub/linuxmint-debian-repositories/pools/B/pool/main/g/gcj-4.7/gcj-4.7-base_4.7.2-3_amd64.deb

sudo dpkg -i gcj-4.7-base_4.7.2-3_amd64.deb 

sudo dpkg -i libgcj-doc_4.7.2-1ubuntu1_all.deb

The same error persists.

I just got the same problem. Any idea ?

Problem is Ubuntu 12.04 LTS - the python-crypto package on this Ubuntu release is still version 2.4.1 - and the required module PKCS1_v1_5.py is missing.

You could install it by manually download the deb package from http://packages.ubuntu.com/quantal/i386/python-crypto or http://packages.ubuntu.com/quantal/amd64/python-crypto

and install it

user@sys:~$ wget http://mirrors.kernel.org/ubuntu/pool/main/p/python-crypto/python-crypto_2.6-2_i386.deb

Afterwards, error should be gone - btw. don't miss to install required python-requests package.

It's working now. Thanks a lot!

That's great help, thanks! Also if you're using a 64bit version of Ubuntu you can use:

wget http://mirrors.kernel.org/ubuntu/pool/main/p/python-crypto/python-crypto_2.6-2_amd64.deb sudo dpkg -i python-crypto_2.6-2_amd64.deb

Now that Ubuntu 13.10 is past the expiration date, the version of the package is not available for 12.04 LTS (14.xx version has several unmet dependencies on 12.04), the solution is to do the following:

cd /opt
#Optional: sudo chown `whoami` /opt
sudo apt-get install python-dev
git clone https://github.com/dlitz/pycrypto.git # May require sudo
cd pycrypto
# Version 2.6.1 works with czdap-tools and 2.7a1 does not
git checkout v2.6.1
./configure
python setup.py build
sudo python setup.py install
