I checked on this laptop BIOS and "secure boot" is disabled. I have to check the tower to see if the same is happening. I believe I had to disable secure boot to install Zorin initially?
Thanks, good to know it's not just me. I clicked on "this post" and read some of suggested actions. I will be able to start on this in a couple of days time when my slate clears.
I did the process. No joy. This was the last msg I received:
bruce@LINUX3:~$ sudo rm /var/lib/fuupd/pending.db
[sudo] password for bruce:
rm: cannot remove '/var/lib/fuupd/pending.db': No such file or directory
bruce@LINUX3:~$
I did the process on my upstairs tower and it did fix the problem. I will re-do the process on my laptop and look more carefully what I type with my 2 fingers. Grateful.
