John Says: Sorry, SSE2 Is Required for This Build

I was following the linux password cracking tutorial. Then when i opened(tried) john i got a message saying Sorry, SSE2 is required for this build. I typed this command to see if I had SSE2 institutions set: cat /proc/cpuinfo | grep flags | tail -n 1 : it said i did. Can any one help me with this problem thx.

btw. I'm running Kali linux 2.0

It is very likely linked to a software reason. Either you installed 32bits system over a 64bits CPU (i386 over amd64), or you may not have the compile tools that are able to handle SSE2 instruction sets. It also may be because the build-system of John has a flaw and failed to detect properly the ability of your system.

Hello there,

Ran into troubles with my Linux Kali2 distro.
I first checked the flags as described above to see I had the SSE2 flag. I did have the SSE2 Flag.
Then, believe it or not, my solution was to type :
"apt-get install john" and then reboot.

Solved the problem for me and hope this will help.
