Top posting: This is the current data from Lubuntu, and that UUID number doesn't show up anywhere in "sudo blkid" from in the Lu system. But I did write that number down from some "error" reports showing in the console during the last apt dist-upgrade that I ran yesterday in Lu. Somehow perhaps apt did something to mess itself up??
[CODE] sudo cat /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_TIMEOUT=0 GRUB_DISTRIBUTOR='lubuntu1910' GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=f9ae531f-ec45-4a13-a75d-d3fd4cd80fe0" GRUB_CMDLINE_LINUX="" [/CODE] Do I want to edit that "quiet splash resume" data to match the /dev/sdc7 location of the Lubuntu "/" UUID?? [CODE] /dev/sdc7: UUID="17bcb813-d05e-4cc3-bcdf-16d283156780" [/CODE] And, then try to again run the grub bootloader to get it to find a newer location of Lu that would then allow upgrading to 5.19 xx kernel???
