I attempted to upgrade again just now. Ran the query. Waited an hour and nothing went wrong. Then upgraded from 4.6.6 straight to 4.6.8 and it seems to have gone right this time. Website hasn't taken it's own life so far.

I will let you know if it does happen again this time though. As it's happened two times before.

Thanks for all the replies 🙂

Found a fix.

If you are using nginx, go into your /etc/nginx config or the config of your specific website in the etc/nginx/sites-available folder.
Edit the config using nano (or any other preffered editor)
Add this line at the bottom of the http or server block and change it to the maximum upload file size you want to allow (I have it set to 200MB):
Either:

http {
    client_max_body_size 200M;
}

Or:
 
server {
    client_max_body_size 200M;
}

save the config and then do: sudo service nginx restart
You are now done and should be able to upload just fine.

Fixed it by deleting the bimchatbox folder from the applications directory and then installing again from the marketplace.

Ended up being php-xml somehow having uninstalled itself after an upgrade.
