Help, ValueError: need more than 2 values to unpack

[Sapto Aji]

i'm following this link sir, null-byte.wonderhowto.com but i get problem like this..

this is setup.py file
`import os, math, sys

#OS_bit = (round(math.log(sys.maxint,2)+1)) # get the bit

os.system("sudo apt-get install python-pip && sudo apt-get install tor") # installing dependencies
os.system("pip install -U selenium")
os.system("pip install Pysocks")
os.system("pip install pyvirtualdisplay && apt-get install xvfb")

#print("\n \n {} \n \n".format(OS_bit))

os.system('firefox -v > tmp') # store result of firefox -v in tmp
result = open('tmp', 'r').read() # result var reads the output
marker = result.find('Firefox') + 8 # marker marks the 8th letter from the word "Firefox"
version = result[marker:].splitlines()[0] # spliting the output, the version is something like aa.bb.cc
a,b,c = version.split(".") # a is the var with the aa
os.remove('tmp') # removing the temporary file

FirefoxVersion = int(a)
second = 0

if FirefoxVersion < 53:

first = 16
second = 1
OS_bit = 64

elif FirefoxVersion == 53 or FirefoxVersion == 54:
print(marker)
first = 18

elif FirefoxVersion > 54:

first = 19

os.system("wget https://github.com/mozilla/geckodriver/releases/download/v0.{}.{}/geckodriver-v0.{}.{}-linux{}.tar.gz".format(first,second,first,second,OS_bit))
os.system("tar -xvzf geckodriver-v0.{}.{}-linux{}.tar.gz".format(first,second,OS_bit))
os.system("rm geckodriver-v0.{}.{}-linux{}.tar.gz".format(first,second,OS_bit))
os.system("chmod +x geckodriver")
os.system("mv geckodriver /usr/local/bin/")
chmod +x faitagram && chmod +x setup.py`

and this the error..
