Apart from the other methods already sent to the list, you can also do As-User> grub-install --version For that I get ;bash: grub-install: command not found And if that doesn't work you do; As-user> sudo grub-install --version FWIW, I have (ascii) grub-install (GRUB) 2.02~beta3-5+deb9u1 So, you just run grub-install and it just runs the last installed version. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

In the second case (su -) it finds the command and fails because you didn't tell it where to put the bootloader.

It seems user has no path to /usr/sbin: $ echo $PATH /usr/local/texlive/2018/bin/x86_64-linux:/home/haines/scripts: \ /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games I was unaware of "su -". Interesting.

You can type # which grub-install and if you don't get a result, your shell doesn't know to look there. You can also try # echo $PATH | grep '/usr/sbin:' to get an immediate, easy-to-read result.

Did not help. That's pretty weird. If you reinstall the grub-pc package, it will run a debconf dialog and ask you where to put the bootloader. I don't know if it operates like that in alternate realities, and i think you might be in one. Check the size on your grub-install. It looks small.
