command-not-found is crashing on a more or less brandnew install

[Can Baysal]

I was testing some software on a raspberry pi 3. For test purposes I installed ubuntu-20.04.2-preinstalled-server-arm64+raspi.img performed full update, installed gcc and friends Then for debugging of network connection I needed netstat which was not installed. Instead of usual package suggestion I got below message. I do not know what corrupted the database, or when that happen. This was my first non existent command on this particular install, so I do not know if it was corrupt to begin with or corrupted in the last 12 hours or so the device was running.
