Please, can someone give me step-by-step instructions how to get back into my Linux Cinnamon operating system.

I updated the definitions. After a reboot this issue appeared.

Every distro I've seen keeps at least one prior kernel version available in grub if not more. My multiple 18.x updated across versions Mint system has 11 at the moment....

So, in the grub menu, select an older kernel, boot that, remove bad kernel, update grub. If you don't see the grub menu press the shift key on your keyboard at the end of the BIOS stage of your computer.

FWIW it looks like the initrd didn't get updated properly either for file system drivers, hard drive controller, etc. OR the reference to the root file system is wrong.

EDIT - to remove the bad kernel, etc.

Get a list of installed kernels on your system -

First, if linux-image-generic is installed remove it. It is a meta package that keeps your kernel up with latest releases. Then remove the offending version.

user@darkstar ~ $ sudo apt-get remove kernel-image-generic
... apt doing stuff ...
user@darkstar ~ $ sudo apt-get remove kernel-image-x.y.z-a-generic

When a new release is made, you can install it specifically and test it - if it works, you can reinstall the kernel-image-generic to keep up to date on releases

  • Thanks very much I chose in the advanced menu a different version. So now that I am in how to I delete the kernel that doesn’t work – tomcolgan Mar 17 '18 at 17:10
