 sudo cp -rPp /usr/src/linux-headers-$(uname -r) /usr/src/linux-headers-$(uname -r).original

 ## disable and remove old:
 sudo systemctl disable --now zfs-zed || true
 sudo rmmod zfs zunicode zavl icp zcommon znvpair spl
 sudo modprobe -rv zfs


 ### INSTALL
 sudo make install; sudo ldconfig; sudo depmod

 ls -la /lib/modules/$(uname -r)/extra/

 ##before make install, remove extra from search of: /etc/depmod.d/ubuntu.conf

 ## usually sudo depmod -a ; sudo modprobe zfs , so do:
 cd scripts
 sudo ./zfs.sh -vr
 #instead of:
 sudo modprobe zfs

 ## if install did not make new module automatically at reboot, do:
 #add extra in search of: /etc/depmod.d/ubuntu.conf
 #and sudo depmod -a ; sudo modprobe zfs
