I’m sorry if this has been asked before, I searched using different terms but couldn’t find a similar question. I’m a noob. When using apt install sometimes it recommends a bunch of other packages. I read that GUI tools generally install them. I don’t use GUI, I use the terminal. I know of the --no-install-recommends flag, but I am wondering whether and when to use it. Should I just let it do the default thing?

For example, this is the list of packages when I try to install Calibre:

Some of them seem useful based on names, but for example blt-demo?
