[GRUB] Kubuntu 20.10 Groovy install fail help

[TJ Wolf]

I’m using MBR Legacy.

Hi i need some help with installing Kubuntu 20.10 Groovy. I have tried to install it 5 times with the same output grub-install /dev//sda failed every time i have switched USB sticks but that is not the cause.

grub-install: error: failed to get canonical path of /cow'.

I always use whole drive and put the / for root. And then install and usually the installer takes care of the grub install on /dev/sda. now having issues. I never had issues like this before.

Thanks for your help in advance Kubuntu
