Suggested Workaround: https://wiki.debian.org/Btrfs
The brtfsck don't support the standard -a option. To haven't this problem you can make it: dpkg-divert --add --rename --divert /sbin/fsck.btrfs.real /sbin/fsck.btrfs And create the executable file /sbin/fsck.btrfs with this wrapper by exemple: /sbin/btrfsck $(echo $@ | sed -e "s/\($1\)\|\(-a\)//g") Thanks to https://wiki.debian.org/MichelBarret Regards, Laurent.
