what is the name of package inside which lsblk exist ?
most likely would give more question such for another Linux executables, as for time being, in difficulty being on "mini" Arch Linux not a real Arch one i.e. MSYS/MingW64 terminal on Windows
Sincere help so invaluable
sudo pacman -Fy lsblk

etc/zfs/zpool.d/lsblk
usr/lib/zfs/zfs/zpool.d/lsblk
So the package is util-linux (from the system repository)

If the package is installed, one can also do
$ pacman -Qo lsblk
/usr/bin/lsblk is owned by util-linux 2.39.2-1
I'm using
sudo pacman -Fy && sudo pacman -Syu && sudo pacman -Sc;sync;sudo fstrim -v /
for Updates. So for search "pacman -F lsblk" is enough and needs no "sudo".
With "pacman -Fl util-linux" u can list all.
I wouldn't recommend using -Sc until after rebooting and checking things still work OK, because that clears the cache of all packages except the currently installed version. If the next boot fails or you have lost network connection you will need to start importing packages on a USB after downloading them elsewhere to downgrade, which can be very time consuming. That's intended for manual use after you have performed manual checks. There are some (very small) AUR packages that work via the pacman hooks feature which clear the cache but leave the currently installed plus previous version, those are designed for automated cache clearance.
I have Backups (via "rsync -vaxH --link-dest=…") and a 1:1 copy of my Installation on an ext. SSD.
If something goes wrong, I boot the ext. SSD and transfer it back (a simple Script to sync the booted OS to the other: usually in ~20 Seconds.), or restore the nedeed Part from a Backup.
No Problem.
Oh, that's good, you have a plan B then , in this case B for Backup! :D
