[Trisquel-users] Re : Can't boot after update

[lcerf]

Check with 'blkid' whether b0fb4364-429c-4573-b0a0-7bddb6bb37ca is the  
correct UUID of the root partition and whether  
/boot/vmlinuz-4.4.0-161-generic exists (it is not the latest version  
available on Trisquel 8).  The change will not be persistent.  If it works,  
executing 'sudo update-grub' may be enough to generate a correct  
configuration.

... or you can reinstall GRUB and, if that works, never know what precisely  
went wrong.
