Comment # 10 on bug 1218864 from Giacomo Comes

I did the metadump after booting in Leap 15.5 and accessing the unmounted
tumbleweed disk image. There was a warning message on stdout while using
xfs_metadump about some unsupported feature of the disk image that were not
compatible with the Leap 15.5 kernel. But I did not mount the disk image.
Let me regenerate the metadump without using Leap 15.5 but only tumbleweed to
access the disk image, this time I'll also add a metadump of the freshly
installed tumbleweed disk image before running any update-bootloader --reinit.
