powerline version from repository is not compatible with fish version

I just installed the powerline apt package on Ubuntu 17.10 and followed the documentation to install it for the Fish prompt, then I got the error below after trying to launch Fish. The {repository_root} of this ubuntu package I am using in my config. file is "/usr/share", which is where the powerline bindings for Fish are located at. Powerline version is 2.5-1.1.

/usr/share/powerline/bindings/fish/powerline-setup.fish (line 35): function: Illegal function name '--on-variable'

I already filed a bug (https://github.com/powerline/powerline/issues/1850) in the powerline project page and they told me to report a bug for this ubuntu package. Can you fix this error?
