Public bug reported:
When i try to install grub on an usb stick without root permissions with
the following command line, i get a misleading error message:
[code]
~$ grub-install --recheck --boot-directory=/media/ubuntu-mate/usbstick/boot/
/dev/sda
Installing for i386-pc platform.
grub-install: warning: disk does not exist, so falling back to partition device
/dev/sda1.
grub-install: warning: disk does not exist, so falling back to partition device
/dev/sda1.
grub-install: warning: disk does not exist, so falling back to partition device
/dev/sda1.
grub-install: error: disk `hostdisk//dev/sda1' not found.
[/code]
This error message is misleading. The disk does exist. The command works
without errors, when i put a sudo in front of it.
The error message should be something like:
"You need to be root to have write access"
There should be a check if grub2 does have write access and if it
doesn't, the error message should tell the user, that he doesn't have
permissions and should change to root or use sudo.
This was tested on Ubuntu 21.10
