Stumbled on the same error during installation of TrueNAS 25.04 on GMKTec NucBox G9 NAS. It turned out that the error was due to the boot partitions mmcblk0boot0 and mmcblk0boot1 switched into read-only mode. I fixed the issue by following the recipe in kernel org note mmc-dev-parts.txt In the boot menu select shell List your block devices $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS ... mmcblk0 179:0 0 58.2G 0 disk ├─mmcblk0p1 179:1 0 1M 0 part ├─mmcblk0p2 …

$ echo 0 > /sys/block/mmcblk0boot0/force_ro
$ echo 0 > /sys/block/mmcblk0boot1/force_ro

Also in the same topic people talks about wiping with dd, so on that not seems i was wrong in case try It
