"make linux && sudo make install" doesn't work?

[upd8er]

Was reading this tutorial (here)on how to install iDevicerestore on ubuntu and I got to the part where you have to make libirecovery by typing in terminal

cd ~/libirecovery
make linux && sudo make install

I do this and i then get this:

make: *** No rule to make target `linux'.  Stop.

Don't know what to do about this because I can't find very much on this so I figured I would open a new issue.

Thanks for your support - upd8er
