[tex-live] Update texlive-bin or not?

[Bob]

A few months ago I installed TeX Live 2018 following the instructions at

https://tug.org/texlive/

I did not use the package manager on linux mint.

Linux mint is now recommending that I update texlive-bin.  I find this 
surprising since I did not use the package manager to install texlive; 
furthermore, the package manager says that texlive-bin is not installed.

Should I install the update or ignore it?

More information about my version of texlive and the changelog for the 
update are given below.
