Upon further investigation I found that there is a subdirectory
/etc/apt/sources.list.d in which I found this:

/etc/apt$ ll sources.list.d/
total 68
drwxr-xr-x 2 root root 4096 2021-08-18 00:28 .
drwxr-xr-x 7 root root 4096 2021-08-18 13:30 ..

-rw-r--r-- 1 root root   97 2021-08-18 00:28 openvpn-aptrepo.list.save

As you can see there are two files which are connected to this:
nilarimogard-ubuntu-webupd8-bionic.list
nilarimogard-ubuntu-webupd8-bionic.list.save

So what is the proper apt command to remove these such that apt understands it
correctly?
