Successfully encrypted a pi zero with a zymkey then locked it to device, however after performing an apt upgrade then reboot the device no longer unlucks the filesystem! is there another command that needs to be run after apt upgrade?
Just tried same thing on a pi3, exactly the same issue. now i have 2 useless zymkeys!!
When you say “locked it to the device” do you mean your removed the ‘cut-2-lock’ tab and put the device into “production mode” ?
Yes, after successfully encrypting the sd cards on both pi’s, I cut the tab
I just ran a standard apt upgrade for all new packages
I had verified that both the micro sds where encrypted
I had power cycled the pi’s many times before.
It was only after issuing the apt upgrade command that they both failed
OK… looking into this… .will come back shortly
Many thanks, can the zymkeys be used again on the same pi’s they are locked to I.e run the encryption on the sd card again?
