This used to work in the past but since recently deleting entries withefibootmgr fails with return value 15. Changing the boot order fails aswell. However, creating new entries does succeed, surprisingly. So it doesn'tseem to be a write permission issue.Display the last boot entry:% sudo efibootmgr | tail -1Boot0023* Debian, kernel 4.0.0-1Trying to delete this entry fails:% sudo efibootmgr -b 0023 -B; echo $?efibootmgr: Boot entry 0023 not foundefibootmgr: Could not delete boot variable: Success15I couldn't find a corresponding bug report or anything related to this issue.So it's probably not a common problem.What could be the issue here and how to fix it?System:Debian stretch/sid, kernel 3.16.0-4-amd64, efibootmgr version 0.11.0
