Answer 1

Actually you only need texlive-formats-extra to get 361 MB of archives, instead of 1,500 MB for texlive-full:

sudo apt install texlive-formats-extra

Answer 2

You can simply install the required package texlive-titlesec via yum (if you are using the RPM packet manager):

yum install texlive-titlesec
