I'm trying to install ca-certificates in my docker container and really having no luck.I can apt-get update, and I can install some other packages, but not curl or ca-certificates. Further, if I run the ubuntu base container and exec -it into it, I can apt-get install ca-certificates there.
Dockerfile:
FROM ubuntu:latestENV http_proxy=http://my_proxy_that_probably_doesnt_matterRUN apt-get updateRUN apt-get install -y apt-utilsRUN apt-get install -y ca-certificatesBash:
docker build .
And here is the log for this step:
