Rebuild fails with "failed to load system roots and no roots provided"

While trying to update our discourse forum I bumped on this problem:

When running these command lines:

mlapeyre@poppy-project discourse]$ cd /var/discourse
[mlapeyre@poppy-project discourse]$ git pull
error: cannot open .git/FETCH_HEAD: Permission denied

[mlapeyre@poppy-project discourse]$ sudo git pull
Already up-to-date.
[mlapeyre@poppy-project discourse]$ sudo ./launcher rebuild app
which: no in (/usr/bin:/bin:/usr/sbin:/sbin)

Your Docker installation is not working correctly

[mlapeyre@poppy-project discourse]$ 

Any idea what could solve the problem ?

What version of docker are you running? Can you try updating to 1.9?

That strongly suggests you don’t have any root CA certificates installed in the machine which you are running Docker on. Without those, HTTPS doesn’t work, because it doesn’t know if the certificates being presented by websites are legit.

Given your prompt style, I’m thinking you’re probably running a RHEL-alike distro, so the package you want to install is probably ca-certificates.


Indeed the problem was a missing file /etc/pki/tls/certs/ca-bundle.crt
