Hello, I was trying to convert a raspberry pi 4 (Raspberry Pi 02 lite 32bit) to mender. The conversion errors out with: `mount: /mender-convert/work/rootfs: wrong fs type, bad option, bad superblock on /dev/loop5, missing codepage or helper program, or other error.` I created the golden image as dd from ```auto Disk: /dev/disk2 geometry: 7764/255/63 [124735488 sectors] Signature: 0xAA55 Starting Ending #: id cyl hd sec - cyl hd sec [start - size] ------------------------------------------------------------------------ 1: 0C 64 0 1 - 1023 3 32 [8192 - 524288] Win95 FAT32L 2: 83 260 0 1 - 1023 63 32 [532480 - 5611521] Linux files* 3: 00 0 0 0 - 0 0 0 [0 - 0] unused 4: 00 0 0 0 - 0 0 0 [0 - 0] unused BMacBook-Pro:input user$ sudo dd if=/dev/disk2 of=sb-no-mender-golden-0.5.1.img bs=512 count=6135810 ``` running: ```auto Running mender-convert --disk-image input/sb-no-mender-golden-0.5.1.img --config configs/raspberrypi4_config Running mender-convert-extract: --config ./work/override_compression_config --disk-image input/sb-no-mender-golden-0.5.1.img --config configs/raspberrypi4_config 2021-12-31 10:19:47 [INFO] [mender-convert-extract] Using configuration file: configs/mender_convert_config 2021-12-31 10:19:47 [INFO] [mender-convert-extract] Using configuration file: ./work/override_compression_config 2021-12-31 10:19:47 [INFO] [mender-convert-extract] Using configuration file: configs/raspberrypi4_config 2021-12-31 10:19:47 [INFO] [mender-convert-extract] Validating disk image 2021-12-31 10:19:47 [INFO] [mender-convert-extract] Disk parsed successfully 2021-12-31 10:19:47 [INFO] [mender-convert-extract] NUMBER OF PARTS: 2 TYPE: dos 2021-12-31 10:19:47 [INFO] [mender-convert-extract] PART 1: SIZE: 256M TYPE: 0xc 2021-12-31 10:19:47 [INFO] [mender-convert-extract] PART 1: extracting to work/part-1.fs 2021-12-31 10:19:57 [INFO] [mender-convert-extract] PART 2: SIZE: 2.7G TYPE: 0x83 2021-12-31 10:19:57 [INFO] [mender-convert-extract] PART 2: extracting to work/part-2.fs mender-convert-extract has finished.

I would start by looking at the image you’ve extracted. Can you get it to mount locally? ---

@oleorhagen not sure how to mount it locally, but if I flash it onto an SD card using RPI imager, the PI is running fine. ---

Hmm, that is interesting. You can mount the filesystem with the `mount` command, if you’re on `linux`. And then give it the right offset for the partition you want to mount.
