Clearing the ePSA Event Log
I wanted to answer the question in this topic, but found that it was already closed, so I am making a new topic for this in this board. I hope that's okay.
The solution to clear the ePSA Event Log was first posted in this topic, but you may get an error message that you do not have permission to delete the file. I found out through this page that some UEFI variables cannot be deleted because they have the immutable attribute set. Simply unsetting this attribute allows you to delete the file representing the variable.
Basic instructions:
Start your system in UEFI mode from a live medium such as an Ubuntu USB stick.
Open the terminal.
Use the following commands in succession:
- sudo su
- chattr -i /sys/firmware/efi/efivars/DIAGEEPROM_VAR-XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
- rm /sys/firmware/efi/efivars/DIAGEEPROM_VAR-XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
Where the Xs are numbers specific to your system (tip: use tab to autocomplete the filename).
Close the terminal and reboot.
I hope this information is useful to someone.

How do you get access to the folder that contains the file DIAGEEPROM_VAR? I booted from an Ubuntu USB drive but I am unable to locate the folder.

I was trying to clear ePSA error logs on my OptiPlex 3020 for such a long time without success.
I was getting some kind of permission error, but your solution worked like a charm.
Thank you for sharing your knowledge.
