This suggests there is a problem with a key which should stored on your system.
Has anything changed recently which may explain this ?
Check to see if the key is present.
Open a terminal by pressing 'Ctrl', 'Alt' and 'T' together.
Type or paste in this command followed by Enter to check if the file exists

If the file exists, this command will tell us more about it.

Copy and paste the results back into this thread.

Please confirm the version of Linux Lite you have installed.
