Problem encountered during installation

[xmkid]

HI everyone, I'm a CS student from China. My English is not good enough, so forgive me if I make some grammar mistakes. I'll try my best to make it as clear as possible.

I was running into a problem when following the instructions of github.com/cmusatyalab/elijah-openstack. It was quite ok when installing OpenStack using DevStack, and I could access OpenStack dashboard. But when I typed in following commands:

$ cd ~
$ git clone https://github.com/cmusatyalab/elijah-openstack
$ cd elijah-openstack
$ fab localhost devstack_single_machine

I got these information:

[localhost] Executing task 'devstack_single_machine'
[localhost] run: cloudlet --version

What can I do to solve this problem?

I've get the same error and Kiryong Ha helped to solve that. First of all he asked me to put here the result os these commands, so i suggest you repeat the commands to see if is the same.

1) $ pip freeze | grep -i crypto
2) $ cat /usr/local/lib/python2.7/dist-packages/Crypto/__init__.py |
grep version
3) $ cat /usr/lib/python2.7/dist-packages/Crypto/__init__.py | grep version

Myr results are:

rodrigo@rambo:~/elijah-openstack$ pip freeze | grep -i crypto
cryptography==1.2.2
M2Crypto==0.21.1
pycrypto==2.6.1
pycryptodome==3.4
You are using pip version 7.1.2, however version 8.1.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
rodrigo@rambo:~/elijah-openstack$
rodrigo@rambo:~/elijah-openstack$ cat /usr/local/lib/python2.7/dist-packages/Crypto/__init__.py | grep version
version_info = (3, 4, None)
rodrigo@rambo:~/elijah-openstack$ cat /usr/lib/python2.7/dist-packages/Crypto/__init__.py | grep version
Various useful modules and functions (long-to-string conversion, random number
version = '2.6.1' # See also below and setup.py
# New software should look at this instead of at version above.
version_info = (2, 6, 1, 'final', 0) # See also above and setup.py

After that the problem is my Crypto lib, on this way the only thing you should do is remove Crypto folder at /usr/lib and /usr/local/lib of python folder above 2.6. After that should work.

Hi @xmkid,

As @ravila pointed out, this is most likely caused by crypto library incompatibility. Could you please run following commands to verify it?

1) $ pip freeze | grep -i crypto
2) $ cat /usr/local/lib/python2.7/dist-packages/Crypto/__init__.py |
grep version
3) $ cat /usr/lib/python2.7/dist-packages/Crypto/__init__.py | grep version

If you have the crypto library both at /usr/local/lib and /usr/lib, that is the reason for the library error. If that's the case, you need to delete one that has version above 2.6. You just need to delete Crypto directory of a higher version.
