You should never get a "logon loop" problem if you do one simple thing to preempt it.

I have told you multiple times but you seem to forget every install you do.

Yup. I don't remember you saying do a simple thing. Only complicated stuff which I have forgotten.

OK, one more time.  Before

OK, one more time.  Before you reboot the system after the installation tells you to reboot, edit the grub file and remove "quiet splash" from the kernel command line. Then update-grub.

One simple edit and the problem is solved. I don't know anything much simpler than a couple of delete keystrokes and an update-grub command in the Terminal.

By tomorrow I hope to have that added to my permanent collection of notes. I will try the fix tomorrow morning. And hopefully regain 500,000 Rac!

I just followed your directions during a delete disk/re-install of Ubuntu 20.

And all I got was "this lousy error message". :)

 

ubuntu@ubuntu:/$ sudo update-grub
/usr/sbin/grub-probe: error: failed to get canonical path of `/cow'.


So much for it being "foolproof".  It was simple.

After reboot with 2 gpus installed was able to run the update-grub.

Have Ubuntu repo version of BOINC installed.  "use_all_gpus" set. And 5 gpus to test running.

Both E@H and Universe at Home are currently processing.  The gpus are single threading for the night.

You have terrible luck with

You have terrible luck with installs I guess.  I have no response other than Ubuntu hates you.

I've never had that error before.

I had to look it up. It seems that you were installing a dual-boot system, correct?

Problem was you didn't have chroot permission to the boot directory where grub resides.

So not a simple fix and way beyond what a beginner would be expected to know and understand.

Sorry for leading you astray.

Wasn't a dual boot system. But way I exited the reboot script may be the issue.

Could be. If you did anything

Could be. If you did anything other than dismiss the notification that the system will reboot now could have been the problem.

That is all I do.  Dismiss the notification and then open a Terminal to edit the /etc/default/grub script to remove the quiet splash and save the file.

Then do a update-grub.  Then I exit the desktop with a restart.

And all is well.
