I'm running bt5r2 now so I'm not sure it's appropriate to post this here, but the problem seems to be extremely similar.

I tried updating sqlmap and experienced failure and now the program won't even run. I removed it, reinstalled sqlmap from the file provided by the sqlmap project on source forge. Unfortunately this did not solve my problems.

Code:
root@bt:~/sqlmap# ./sqlmap.py --update
