I’m trying to upgrade my SLES12 SP4 lpar (ppc64le) to SLES15 SP1.
So it is an offline upgrade.
But for security purpose, our systems dont have access to internet except if I run few commands (export PROXY variables, copy and trust its certificat with a c_rehash command).
While booting on the Installer iso file and run the Upgrade wizard, I cant find a way to configure my proxies in order to access Suse internet repositories.
Please how can I configure my proxy (Zscaler) in the upgrade wizard ?
I dont manage the proxy, so I cant disable it or rules.
