sudo / lock screen password keeps resetting to default

[ergo owl]

This is the second time I have installed mobian on the eMMc of my Pinephone UBPorts Edition.

The first time I changed the password from the default "1234" using the terminal emulator with the
command "sudo passwd" and it worked.

However, after making some annoying changes I couldnt revert, I decided to reinstall everything and now,
when I try to change the password in the terminal emulator using the same command "sudo passwd", it says:

passwd: password updated successfully

But, when I lock the screen and then attempt to unlock it with the new password. It doesnt work.
When I try with the default "1234" password it works like if I had never changed it "successfully".

Not sure what is happening or what Im doing wrong, maybe Im just tired. Any ideas?

Reboot.

Reboot.

Yeah that doesnt fix anything for me. When I type the password I "successfully" set in the terminal it reads "Checking..." and then fails to unlock.
I put the original passcode "1234" and the screen unlocks.

how about sudo passwd mobian, or just passwd (think you need the sudo to avoid moans about numeric only password?)
