List repositories

=================

List subscription repos::

  sudo subscription-manager repos --list

List enabled repositories::

  sudo dnf repolist

  sudo dnf repolist --enabled

List disabled repositories::

  sudo dnf repolist --disabled

Activate repository::

  sudo subscription-manager repos --enable $REPO

List packages

=============

List all installed packages::

  dnf repoquery --installed

List packages selected by a user (but not automatically to meet dependenciy requirements)::

  dnf repoquery --userinstalled

  dnf history userinstalled

List packages in a repository::

  dnf repository-packages $REPO list

Check package details

=====================

Check if a package is installed::

  dnf list $PKG

  rpm --verify $PKG

  rpm -V $PKG

Check a package version::

  dnf info $PKG

Check repository/origin availability::

  dnf whatprovides $PKG

List package's files

====================

::

  dnf repoquery -l $PKG

  rpm -ql $PKG

Find packages a file belongs to

===============================

Using remote metadata::

  dnf provides ifconfig

  dnf repoquery --file /usr/sbin/ifconfig

Using installed package DB::

  rpm -qf /usr/bin/rpm

Limit search to a specific repository::

  dnf repoquery --disablerepo=* --enablerepo=$REPO -f $PATT

List package dependencies

=========================

::

  repoquery --requires --resolve $PKG

If you possess a actual RPM::

  rpm -qpR $RPM

List of packages that depend on a given

=======================================

::

  dnf repoquery --alldeps --whatrequires $PKG

  dnf repoquery --installed --whatrequires $PKG

  rpm -q --whatrequires $PKG

Dealing with streams

====================

Streams group related package at specific compatible version. Only one version could be installed in

system in time.

For example Node.js has lots of parallel versions::

  bash# sudo dnf module list nodejs

  Name   Stream Profiles                              Summary

  nodejs 10 [d] common [d], development, minimal, s2i Javascript runtime

  nodejs 12     common [d], development, minimal, s2i Javascript runtime

  nodejs 14     common [d], development, minimal, s2i Javascript runtime

  nodejs 16     common [d], development, minimal, s2i Javascript runtime

  nodejs 18     common [d], development, minimal, s2i Javascript runtime

You select specific stream::

  sudo dnf module install nodejs:18

In order to change stream one need to remove all the packages from original stream and reset the

stream::

  sudo dnf module remove nodejs

  sudo dnf module reset nodejs

  sudo dnf module install nodejs:16

Subscription manager
