Bug#592834: grub-efi-amd64: File descriptor leaked on lvs invocation



Hey there, got this warning, dunno why, never read this before.

Here's what I did before I got this warning.
Be aware that I use parrot 4.6, which is based on debian but is a
rolling distribution.

The not upgraded (helt back) packages are some nvidia packages, not
needed on my system (no nvidia card installed). They has nothing to do
with grub.

Maybe this helps you to recreate this issue.


grub-efi-amd64   2.04-1parrot1

PS: memtest86+ does not work from grub for me, that's why I'm trying
"something", not sure if anything helps.
