Upgrades to computer--how?

How do I fix this, with step-by-step directions.
E: dpkg was interrupted, you must manually run ‘dpkg --configure -a’ to correct the problem.

I’m running Linux mint 20.3 cinnamon version 5.2.7.

Just enter the command on the command line…

sudo dpkg --configure -a

There are two minus signs before configure

typed command in terminal window. What do I do next?

Just repeat whatever you were trying to do when you got the error message
