[Bug 1936381] Re: package grub-pc 2.04-1ubuntu35.6 failed to install/upgrade: installed grub-pc package post-installation script subprocess returned error exit status 127

[Julian Andres Klode]

Thank you for your bug report. I don't understand how your touchpad not
working is relevant to your bootloader not installing, please open a
separate bug for that.

For the bootloader issue, it seems  you broke your /etc/default/grub,
please go ahead and fix it back up.

/var/lib/dpkg/info/grub-pc.config: 13: /etc/default/grub:
GRUB_CMDLINE_LIN: not found
