How to tell how a package was installed?

[Manuel Reimer]

Hello,

I've freshly installed an Fedora VM.

If I run "dnf history userinstalled", then I only get 19 packages listed.

That's way less than I would have expected.

For example I have LibreOffice right with my fresh installation. It is 
not listed as "userinstalled".

Even though it is not listed, "dnf autoremove" doesn't ask me to 
uninstall LibreOffice. So somehow it was installed in a way that makes 
"dnf autoremove" know that LibreOffice was "user installed".

What exactly does qualify LibreOffice, Firefox and others to not get 
listed in "dnf autoremove"? Some kind of group? How to find out such 
information?

I assume you installed Fedora Workstation, which provides Gnome 3 and
LibreOffice

From "man dnf":

       dnf history userinstalled
              Show  all  installonly packages, packages installed outside
of DNF and packages not installed as depen‐
              dency. I.e. it lists packages that will stay on the system
when Auto Remove Command or  Remove  Command
              along  with  clean_requirements_on_remove  configuration
 option set to True is executed. Note the same
              results can be accomplished with dnf repoquery
--userinstalled, and the repoquery command is more  pow‐
              erful in formatting of the output.

This points you to "dnf repoquery"

Try:  dnf repoquery --queryformat "%{name}: %{reason}" --installed

You will see that libreoffice packages have reason "dependency".  Packages
you installed have reason "user".   There are also packages with reason
"group",
"unknown", and "weak-dependency".
