Dear Maintainer,

I'm getting an error 10 in post-installation script when updating package grub-
efi-amd64.

I get same result if package is uninstalling (purge) and then install again.

Thanks,
Pablo Pascual

Since you can reproduce this, please try with DEBCONF_DEBUG=developer
set in the environment and post the output.

Thanks,

Here is the output:

After this, I have reinstalled "ucf" package and the error is gone out.

Thanks a lot for your help!

Sincerely yours,
Pablo
