I recently came across an issue with RedHat's yum where I couldn't do anything with it. The error was,

    [root@desktop ~]# yum update
    Loaded plugins: langpacks, presto, refresh-packagekit
    Traceback (most recent call last):
      File "/usr/lib/python2.7/site-packages/urlgrabber-3.9.1-py2.7.egg/urlgrabber/grabber.py", line 1522, in _progress_update
        if self._over_max_size(cur=self._amount_read-self._reget_length):

This was caused by having both the python module urlgrabber from easy_install and the python-urlgrabber RPM installed.

To fix it, I did:

[root@desktop ~]# rm -rf /usr/lib/python2.7/site-packages/urlgrabber*
[root@desktop ~]# rm -f /usr/bin/urlgrabber
[root@desktop ~]# rpm -ivh --force http://hany.sk/mirror/fedora/releases/16/Everything/x86_64/os/Packages/python-urlgrabber-3.9.1-10.fc15.noarch.rpm

When installing Arachni on a default Fedora I was disappointed that it wouldn't work with the standard ruby install (1.8.6). You will need version 1.9.2 which is easy to accomplish with RVM. RVM is fairly simple to install and can be accomplished by running


bash -s stable

Edit your .zshrc or .bashrc and add:

if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then source “$HOME/.rvm/scripts/rvm” ; fi


Then source your .zshrc or .bashrc:

source ~/.zshrc


Then install the new version of ruby you want.
rvm install 1.9.2
