Hey Everyone, as you can see by my title I'm having some issues installing Firefox-ESR on my RPi 3 B+, when I go to the terminal and enter
>>> sudo apt-get install iceweasel
it starts the downloading process ask me if I would like to continue with installing since it needs so many Mb's, so I enter Y, than an error appears and says
Err http://mirrordirector.raspbian.org/raspbian/ jessie/main firefox-esr armhf 45.5.0esr-1~deb8u1

Can anyone tell me what's wrong with the install and how can I fix it Thanks
