Description

I have an IMX8MP-axon-wizard, I was able to install mender and did some tests. I was able to do a update release with no problem. I modify my image to have the data partition encrypted. And now when I try to do an update I get this error:

I also tried doing it manually by executing: mender-update install imx-image-core-axon-imx8mp-0.3.1.mender. And I got this:

I’m confused on why this is happening.

Hi @zetacu,

Thanks for reaching out! Hitting an error in the Download stage is definitely strange. Not sure if that relates to the changes concerning encryption or not. Maybe you can go digging a bit where it falls over?

The actual implementation of this stage is in /usr/share/mender/modules/v3/rootfs-image, you can see the sources at mender/support/modules/rootfs-image at 9b7c9806687279d66c9fbbfdd1154ac487619397 · mendersoftware/mender · GitHub.

I would suggest to add some debug output there to try and find out which actual command fails, and then work from there.

Greetz,
Josef
