grub-install is failing when setting boot variables.  Several possible causes.  To aid troubleshooting is it possible to provide any context at all ?

For example
Is this a dual boot system perhaps ?
Has it been working ok ?
What changed since it worked ?
Does the system boot regardless ?

Assuming you can boot the system, the output of

Code:

efibootmgr -v

Code:

df | grep /boot/efi

will show us some information about the systems boot options which may help work out what is happening.

Thanks for your reply Stevef. No problem with the boot - all working ok. It was just that update that came through yesterday. The os IS working perfectly. It reall y is a puzzle and today I've just updated normally and all ok. No errors. I think it may have righted itself but I'l get back if any further issues. Thank you again.

[stevef]

You're welcome. There have been a couple of threads started recently which may indicate something a bit odd going on with the current round of updates and the linux boot loader (grub).
Hard (for me) to understand exactly what is happening and why.
