Zorin os pro 16.3 shutdown shows lines of code

I had not run the sudo apt autoremove.
I ran the sudo apt purge ubuntu-business-defaults and at the end it told me to run sudo apt autoremove.
I did run that and one line read: dpkg: warning: while removing linux-headers-5.15.0-94-generic, directory '/lib/modules/5.15.0-94-generic' not empty so not removed.

Should I do something further to remove what it said wasn't removed?
I ran the update and upgrade lines again.
If you need more info, like the complete pages of these I can show them.
Now I will try the shutdown and see if I still get the many lines of code like my blurry picture shows.
