sudo throw error cannot execute binary file exec format error

Question

I made a mistake while trying to install Rstudio in a debian with this command:

sudo gdebi rstudio-server-1.2.5033-amd64.deb

and now if I try to use sudo again, I ve got this message :

sudo apt-get update: bash: /usr/bin/sudo : cannot execute binary file: Exec format error

How can I reverse this error ?

Thanks
