can't ssh into remote machine using blowfish

I have a remote machine I need to ssh to using blowfish encryption. I set everything up on my laptop on my previous distro and I have in my config file setup for blowfish. Today I install Ubuntu Gnome and when I try to ssh to whatever machine I get an error

/home/yotam/.ssh/config line 43: Bad cipher 'blowfish'.

I searched what I need to install, but it seems that this should come with the distro. What am I missing?

There is no cipher called blowfish in SSHv2. It was only in the old protocol SSHv1, which is gone (hopefully also on Ubuntu).

SSHv2 has cipher called blowfish-cbc as pointed out in manual page for ssh_config (always good place to start).
