Latest update creates warning when running apt

[oshunluvr]

I did the HUGE update to 6.7 this morning. As is my habit I did so from the terminal. When it was done, I rebooted then ran "apt update" again to make sure everything was upgraded.
I then got this warning:

All packages are up to date.
N: Ignoring '20apt-esm-hook.conf' in directory '/etc/apt/apt.conf.d/' as it is not a regular file
Listing... Done
N: Ignoring '20apt-esm-hook.conf' in directory '/etc/apt/apt.conf.d/' as it is not a regular file

A little sleuthing revealed:

$ ls -l /etc/apt/apt.conf.d/20apt-esm-hook.conf
lrwxrwxrwx 1 root root 34 Jun 19 10:36 /etc/apt/apt.conf.d/20apt-esm-hook.conf -> ../../kde_neon/20apt-esm-hook.conf

Digging a bit more:

$ cat /etc/kde_neon/20apt-esm-hook-neon.conf​
# KDE neon diversion to remove ubuntu advantage bits

Although the symlink appears correct; i.e. doing "ls ../../kde_neon" from the /etc/apt/apt.conf.d/ directory does indeed reveal "20apt-esm-hook-neon.conf", the link still appears broken.

Although removing the symlink doesn't appear to have any ill effect, I recreated it using "/etc/kde_neon" instead of "../../" and the link now works. I have no idea why it didn't before. Code to create the new symlink:

sudo ln -s /etc/kde_neon/20apt-esm-hook-neon.conf /etc/apt/apt.conf.d/20apt-esm-hook.conf
