I waited maybe tool long to perform upgrade procedure. I keep getting the following error which maybe is preventing new updates from being installed.
samba-kdc-32bit-4.7.11+git.186.d75219614c3-lp150.3.18.2.x86_64 requires libkdb5.so.8, but this requirement cannot be provided
kdepim-runtime-18.12.3-lp151.2.4.1.x86_64 requires libQt5NetworkAuth.so.5()(64bit), but this requirement cannot be provided
Not entirely clear what your problem is or what you are trying to achieve, but a copy of the last packages for the discontinued Leap 15.0 is still available here:
https://ftp.gwdg.de/pub/linux/suse/opensuse/update/leap/15.0/
So if you just need a few packages, download from there, install manually, then upgrade to 15.1 ASAP.
I already had 15.0 installed. Was following instructions how to upgrade to 15.1. I think I answered somethings incorrectly so some updated packages were not download. I decided to upgrade through the downloaded ISO. That fixed it. So that is why I am not more detailed here.
