Trouble using "zypper addrepo" with http proxy and certs

SUSE Linux Enterprise Server SLES Networking
1

I am trying to setup a SLES 11 SP4 VM in Virtualbox to use a specific http proxy for all traffic along with certs exported from Windows.

I have successfully added the proxy and certs to Firefox so that Firefox works without problems. I also have the http_proxy and https_proxy environment variables set to the proxy URL.

Now I am trying to get zypper to work. My specific test case is to try and add the repository needed to install git. I will include the output below. I also tried to retry without the SSL verification but the result was the same error as before.

[CODE]$ sudo zypper addrepo https://download.opensuse.org/repositories/devel:tools:scm/SLE_11_SP4/devel:tools:scm.repo

Interestingly I could use curl to download the content of the address, but only if I passed the --insecure flag.

[CODE]$ curl --insecure https://download.opensuse.org/repositories/devel:tools:scm/SLE_11_SP4/devel:tools:scm.repo

Any ideas how I can approach solving this?

Is the IPv6 address above your proxy as set for http_proxy and
https_proxy? To be honest I’ve never tried setting an IPv6
address only IPv4.

Have you seen TID 7006845[1], particularly the reference to
/etc/sysconfig/proxy ?

HTH.

The IPv6 address is my proxy. I assumed it was the repository’s address.

[QUOTE]Have you seen TID 7006845[1], particularly the reference to

Thanks for the resource. I haven’t seen it. I edited /etc/sysconfig/proxy and set both the HTTP and HTTPS variables to point to my HTTP proxy, logged out and back in and now zypper works (albeit with disabling SSL Verification)!

If your proxy terminates SSL, you need the proxy’s certificate as a trusted CA.
In order to have this, copy the PEM encoded certificate to /etc/ssl/certs and do a

c_rehash /etc/ssl/certs

on SLES11. On SLES12 you’d need to use the /etc/pki/trust/anchors directory and call

update-ca-certificates

See the rpm -q --scripts openssl-certs (SLES11) or rpm -q --scripts ca-certificates (SLES12) output if in doubt.
