Error mounting IMG (wrong fs type, bad option, bad superblock)

[ondrejhajek]

Hi,

i have problem like in this #176

2 different machines (both Linux Mint 20.2 based on Ubuntu 20.04, x86_64) and i get error:

mount: /mnt/sdm: wrong fs type, bad option, bad superblock on /dev/loop26, missing codepage or helper program, or other error
mount: /mnt/sdm/boot: mount point does not exist
? Error mounting IMG '2023-12-11-raspios-bookworm-armhf-lite.img'

i run command from documentation: sudo sdm --customize --plugin user:"adduser=bls|password=mypassword" --plugin L10n:host --plugin disables:piwiz --regen-ssh-host-keys --restart 2023-12-11-raspios-bookworm-armhf-lite.img

sdm v11.4

mini-nspawn output is ok without errors

i work with freshly downloaded latest 2023-12-11-raspios-bookworm-armhf-lite.img image

thank you

[ondrejhajek]

i have found error in linux dmesg:

EXT4-fs (loop40): VFS: Can't find ext4 filesystem

[gitbls]

As I mentioned previously, I installed Mint 20.2 and am unable to repro this.

I do have one idea for what the issue might be, but I'd really like a repro to test it. Any thoughts on how you could create a reliable repro for me?

[gitbls]

One thought: Can you burn an ssd or sd card and then try to mount it with sudo sdm --mount ...?

If this works on the mint system that mounting the IMG is failing, then I have a good idea as to how to fix.

[ondrejhajek]

@gitbls done, i successfully burnt with sdm img to medium and i was able sdm --mount this medium

[gitbls]

Thx. That confirms for me that it's a bug in old Ubuntu and Mint releases, and will work around it.

[gitbls]

Please try the sdm-cparse in the attached zip file:

• Unzip it
• cd /usr/local/sdm
• sudo mv sdm-cparse sdm-save-cparse
• sudo cp /path/to/new/sdm-cparse sdm-cparse

Try the --mount command that previously failed. Please capture and provide all console output if it fails.

sdm-cparse.zip

Yes, I know this can be done with a github branch

[ondrejhajek]

sudo sdm --customize --plugin apps:"apps=@myapps" 2023-12-11-raspios-bookworm-armhf-lite.img

i get this error:

* Mount IMG '2023-12-11-raspios-bookworm-armhf-lite.img'
mount: /mnt/sdm: wrong fs type, bad option, bad superblock on /dev/loop40, missing codepage or helper program, or other error
? IMG '' already attached to a loop device

[gitbls]

OK, thx. Will instrument up more logging to see what's going on.

[gitbls]

This one should put out some logging (so i can see where it's erroring out). Same "install" as before, but you don't need to save the one I previously sent you.

here is output:

* Mount IMG '2023-12-11-raspios-bookworm-armhf-lite.img'
Before 'new' mount
mount: /mnt/sdm: wrong fs type, bad option, bad superblock on /dev/loop40, missing codepage or helper program, or other error
Before 'old' mount
? IMG '' already attached to a loop device

[gitbls]

Strange. Investigating...

[gitbls]

Please try this version.

there are some errors, but i think it works:)

in output, there are czech words, translation:

Great! I will make the "odpojenf" and the "Delete dangling loop devices" messages go away, so it will be pretty seamless.

This will be in the next release, coming soon. I'll update this thread when it's available.

[gitbls]

one more thing. Could you check and see if there are any unexpected, sdm-ish looking loop devices hanging around after you run sdm?

sudo losetup -a

Thx

i see only my snap applications

[gitbls]

Could I convince you to try this updated version just to make sure I didn't duff it?

[gitbls]

Thanks!

[gitbls]

This is all fixed 🤞in V11.5. Please test/verify. Thx!

[ondrejhajek]

v11.5 is ok

[gitbls]

Excellent. Thanks for helping me sort this out. Still strange that I coudn't repro it here on Mint 20.2 😵
