- - grub2 <unfixed> (unimportant)
- NOTE: Issue does not affect standard SB Debian setup.

than the one in
+ NOTE: Ubuntu and returns the code from "shim not available" and "kernel
signature
+ NOTE: verification failed". The patch for CVE-2020-15705 is essentially
about handling
+ NOTE: those two cases in the same way when they were previously handled
differently,
+ NOTE: and so not a problem for src:grub2 in Debian.
