1. go to http://dl.hhvm.com/ubuntu/pool/main/h/hhvm/ and right click and copy the link to the version of hhvm you want to rollback to
2. sudo apt-get autoremove hhvm -y
3. wget <link you just copied>
4. sudo dpkg -i <name of file u just downloaded>
5. apt-get install -f
6. service hhvm start

Edit: Don't worry when it errors out on step 4. that is expected. just continue to step 5.
