EOL is not until 4/26/23.  If this is truely an LTS release my
understanding is it should be stable and reliable until the EOL date. 
Please don't tell me to update my entire system to fix this. There are
some people that appreciate stability that run a release until close to
it's eol before upgrading.  As far as I understand (and I could have
made an error) the 180 kernel came from a standard update from
bionic-updates/main or bionic-security/main.  This was installed with:

apt-get update

apt-get dist-upgrade

I don't believe I have any repositories in my sources.list that would
install cutting edge kernels.

:/etc/apt# apt-cache policy linux-image-4.15.0-180-generic 
linux-image-4.15.0-180-generic:
  Installed: 4.15.0-180.189
  Candidate: 4.15.0-180.189
  Version table:
 *** 4.15.0-180.189 500
        500 http://mirrors.namecheap.com/ubuntu bionic-updates/main amd64 Packages
        500 http://mirrors.namecheap.com/ubuntu bionic-security/main amd64 Packages
        100 /var/lib/dpkg/status

Here's my /etc/apt/sources.list minus the comments...

/etc/apt# cat sources.list | egrep -v '^#'

deb http://mirrors.namecheap.com/ubuntu/ bionic main restricted
deb http://mirrors.namecheap.com/ubuntu/ bionic-updates main restricted
deb http://mirrors.namecheap.com/ubuntu/ bionic universe
deb http://mirrors.namecheap.com/ubuntu/ bionic-updates universe
deb http://mirrors.namecheap.com/ubuntu/ bionic multiverse
deb http://mirrors.namecheap.com/ubuntu/ bionic-updates multiverse
deb http://mirrors.namecheap.com/ubuntu/ bionic-backports main restricted universe multiverse
deb http://mirrors.namecheap.com/ubuntu/ bionic-security main restricted
deb http://mirrors.namecheap.com/ubuntu/ bionic-security universe
deb http://mirrors.namecheap.com/ubuntu/ bionic-security multiverse

So I don't believe that I've done anything which would have installed
anything but the default standard kernel.

If I am wrong, please let me know.

vmlinuz-4.15.0-180-generic was installed using
apt-get update
apt-get dist-upgrade
