A distribution upgrade failed on mail.eskimo.com leaving the machine in an unbootable state where grub failed to install properly.
An attempt to install grub2 manually results in can not write EFI variables to NvRAM. I’ve not encountered this on a virtual machine before and not being successful at finding info on how to fix. The easiest thing may be to just rebuild the virtual machine from scratch and then restore all the files. I have a few other things I’m going to try first but before I do I’m making a current backup of the mail spool to make sure we do not lose any mail. This may take several hours.
