Bug 1174030

Hello,
I've also posted this at the Opensuse Forum.

Of note: my /home is on a separate XFS partition of the same drive, and I ran updates and rebooted before attempting the upgrade.

I tried upgrading Leap from 15.1 to 15.2 via USB since all I have is Wifi atm (so ctrl+alt+f2 -> root login -> 'init 3' -> 'zypper dup --download-in-advance' is a fail due to losing Wifi in runlevel 3). So I disabled other repos in advance and upgraded Opensuse repos to 15.2.
During the install, it reached approximately 85 - 90% completion, and then started throwing read-only errors during the attempt to install xorg-x11-xvnc, and all packages afterwards. So at this point the upgrade was damaged.
I force-rebooted and selected to boot from the snapper snapshot I made prior to the upgrade. Great - it booted... except 'su snapper rollback' resulted in an error to the effect of, "Couldn't create snapshot ((error 30) - read-only filesystem)". So snapper couldn't make a backup copy of the current ro filesystem and, consequently, couldn't set the current ro image to rw. So, I tried booting from the installation USB in recovery mode and mounting the partition as rw so I could check the /etc/fstab, but received "wrong fs type, bad option, bad superblock on /dev/sda2". Looking it up, a Suse document recommended btrfs rescue zero-log, which succeeded only in destroying it further; so much so that the ro snapshots would not even mount.

Now...
I have reinstalled from the ground-up, preserving my home partition, in the following manner:

-During partitioning, I selected Advanced partitioning and selected:
1. Reformat the btrfs system partition, set mount to /, enabled snapshots.
2. Reformat the swap partition, mount as swap
3. Do Not format home partition, mount as /home

-Then:
At user creation, I selected to import a user and selected my username that appeared below.

Installed, reboot, and... my home folder appears to be completely reset; everything - but the stock folders - is gone, and all of my wallpapers in /home/(myname)/.local/share/wallpapers are also missing.
