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

Floreated

Package is named differently on pacman: $ sudo pacman -S texlive-formatsextra – Kaisership

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

Emblem

Answer 3

I did need to install the texlive-full package. It have the titlesec.sty file. The textlive package does not contains the file.

Answer 4

You need to reinstall MikTeX and install the full MikTeX package (not just the basic package). Took like 10 years to update everything. After that just open a document with LyX and after reconfiguration everything should work.
