Fail to install package when building docker image

Question

I use following code to add gdal to my docker image:

FROM node:7-onbuild

RUN apt-get -y update && apt-get -y install software-properties-common 
python-software-properties
RUN add-apt-repository ppa:ubuntugis/ppa
RUN apt-get -y update && apt-get -y install gdal-bin

It always returns error when executing apt-get -y update after add-apt-repository :

W: Failed to fetch 
http://ppa.launchpad.net/ubuntugis/ppa/ubuntu/dists/jessie/main/binary-amd64/Packages  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

I have added --no-cache when executing docker build .

Any idea about the error?

Answer 1

That is because the node image is debian jessie based. The ppa you have added is for ubuntu different versions and not debian

Thats why your url gives a 404. You can check in browser too " http://ppa.launchpad.net/ubuntugis/ppa/ubuntu/dists/jessie/main/binary-amd64/Packages "

You need to find a debian:jessie ppa for the packages you are interested in
