Trying to do a ‘sudo apt-get update’ on my Raspberry Pi running Jessie I got this error:
$ sudo apt-get update
E: The method driver /usr/lib/apt/methods/https could not be found.
N: Is the package apt-transport-https installed?
Seeing posts online with similar errors about the sources configured in /etc/apt/sources.list, I looked in my file and I had this line:
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
I haven’t used or tried to update this Pi for a while so I can’t remember if this line was how it was originally configured or if I changed it.
Replacing this first line with what I think is more typical:
deb http://raspbian.raspberrypi.org jessie main contrib non-free rpi
and then doing a ‘sudo apt-get update’, it updates sources and now I can upgrade and install other packages again as expected.
