[Bug 1539997] Re: package grub-efi-amd64 2.02~beta2-9ubuntu1.7 failed to install/upgrade: subprocess installed post-installation script returned error exit status 127

Hi Phillip (I am asssuming you are a person and not a computer),

Perhaps instead of saying "you edited your ...grub file ...and fouled it
up" you should write "your grub file was edited ...and fouled up" since
I (me, the person) did not edit the grub file.  I don't even know what a
grub file is.

In addition, I cannot tell if your message indicates the problem or the
solution.  Please assume that I am an idiot (new to ubuntu/linux, noob,
or whatever) and that I have no clue what you are talking about.

It sounds like there is a solution, but I need the details spelled out
so that I know what needs to be done.  For example, perhaps it goes like
this?

1) find grub file
2) open editor to edit grub file (probably need admin privileges)
3) change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" usbhid.quirks=0x0c45:0x7603:0x4
   to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" "usbhid.quirks=0x0c45:0x7603:0x4"
[ (i.e., include last part in quotes), or whatever the correct correction is -- it is hard to tell exactly what needs to be done]

Could you or someone please let me know if this is the correct solution,
or please post the correct solution?

Thanks!
Joe
