Can't run msfconsole in kali 32bit ?

Tried running msfconsole in kali 32bit and got lots of error messages starting with something like "bignum too big to convert into `long' (RangeError)" ? 

Turns out there is a simple solution (found it on rapid7's github discussion): 

1. sudo apt-get update
2. sudo apt-get install metasploit-framework
   # pay attention for user-input that is necessary to proceed with installation:
    1) updates notification
    2) services restart (twice) 

Now you can run msfconsole.... 

kali update fails with GPG error ?

Trying to update kali but fail with GPG error ? 

Turns out that if you haven’t updated your Kali installation in some time the repository key expires... 

how to update it ? 

wget -q -O - https://archive.kali.org/archive-key.asc | apt-key add

now your apt-get update will work....
