after doing apt-get update and upgrade , there is sill some problem and to fix those problem :
we install esmre from the source

then we do : cd usr/share/w3af

then : git checkout feature/module

then

sudo pip install PyGithub==1.21.0 chardet==2.1.1 futures==2.1.5 pyOpenSSL==0.13.1 scapy-real==2.2.0-dev msgpack-python==0.2.4

, lease investigate this bugs dev , for me after doing all those steps the problems gone and it is working fine ,

another way to fix it:

we install esmre from the source

cd w3af/
git pull
git checkout feature/module

then in the home folder we show the hidden folders and cd to the w3af and delete the old profile and past the new one ( profile folder)

Saberzaid, the workaround you suggest will mess up your system with non-packaged files and can cause unexpected problems in the future.

I couldn't reproduce the problem described here. What version of w3af & w3af-console do you have installed?

The w3af-console package depends on python-esmre already. So you must have that package installed. If yes, what version do you have?

Please paste the output of “reportbug --template w3af-console” and “reportbug --template w3af”. Thank you.

im using the ver from the kali repo (1.5) you can try to run w3af from your system after apt-get update and apt-get upgrade

and see , it will not work , or ist working with you fine?

root@kali:/usr/share/w3af# ./w3af_console

Apologies, i have set up a new system from scratch, and have managed to confirm this bug.

I uploaded w3af_1.5-0kali2.dsc that should fix the issue for people who upgraded from 1.2 to 1.5. Please let me know if this didn't work out as expected.
