Install Whatsapp on Ubuntu 12.04, 12.10, 13.04, 13.10, 14.04, Mint 13/14/15/16/17

While I would recommend you to simply go for Viber instead, because it’s available for all operating systems; Here’s how to do it for whatsapp. However, if the same number is registered to two devices, Whatsapp doesn’t like you accessing both simultaneously. I’ve read, one at a time works fine.

sudo apt-get install python python-dateutil python-argparse
sudo wget https://github.com/tgalal/yowsup/archive/master.zip
sudo unzip master.zip
cd yowsup-master/src
cp config.example yowsup-cli.config
vi yowsup-cli.config #(Write the following according to you)
#cc=34
#phone=34123456789 #(Phone number with country code)
#id=
#password=
chmod +x yowsup-cli
./yowsup-cli --requestcode sms --config yowsup-cli.config
#status: sent
#retry_after: 3605
#length: 6
#method: sms

You will receive an sms with a code on the above written mobile number. Use that in the next request.

./yowsup-cli --register 123-456 --config yowsup-cli.config (replace 123-456 with the code)
#status: ok
#kind: free
#pw: S1nBGCvZhb6TBQrbm2sQCfSLkXM=
#price: 0,89
#price_expiration: 1362803446
#currency: EUR
#cost: 0.89
#expiration: 1391344106
#login: 34123456789
#type: new
cat yowsup-cli.config
cc=34
phone=34123456789
id=
password=S1nBGCvZhb6TBQrbm2sQCfSLkXM=

If you don’t have pidgin, install it (From software center or by sudo apt-get install pidgin in terminal) Now open a terminal and write

sudo add-apt-repository ppa:whatsapp-purple/ppa
sudo apt-get update
sudo apt-get install pidgin-whatsapp

Now simply launch Pidgin. Add a whatsapp account, put username as the phone number with country code ( as written above) and password as the string we obtained earlier. Use whatsapp on your laptop. (PS- Don’t use it simultaneously on your mobile) Better still, use viber, and ask your friends to do the same! : it has a desktop client.

Edit : If you’re having trouble registering the number on whatsapp, you can use this service here.

Update : The latest update to whatsapp has broken the functioning of the yow-sup api used here.
The issues have been created and developers are working on it. Hopefully it will be sorted soon, but till then, all we can do is wait.
