No Release File

In the file:

I changed:
deb tricia nginx
deb bionic nginx

Then the "apt-get update" worked.

However, I used the Mint Software Manager to install Nginx, but the progress
indicator stalled at about 80%. I closed the Manager acknowledging the
message that a task was still running.

Of course, that probably caused another problem: 
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource
temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend),
is another process using it?
I work on that later.
