Inputs I pick:
:: Replace libusb with core/libusbx? [Y/n] y
:: systemd-tools and udev-oxnas are in conflict (udev). Remove udev-oxnas? [y/N] y

Installation fails with:
error: failed to commit transaction (conflicting files)
filesystem: /var/lock exists in filesystem
filesystem: /var/run exists in filesystem

I tried searching the forum with similar error, but threads go into other details of not being able to mount. I am not too bent on upgrading, but like to get the latest version of everything. Please help with the above errors to safely upgrade the system.
