Description of problem: When running `dnf debuginfo-install [packagename]` for a package which does not exist, there is no warning or error. Version-Release number of selected component (if applicable): dnf-plugins-core-2.1.5-1.fc27.noarch How reproducible: always Steps to Reproduce: 1. run `dnf debuginfo-install foo` or `dnf debuginfo-install xorg-x11-server-xwayland` 2. watch output 3. Actual results: No warning. DNF exits with "nothing to do" message. Expected results: Give a warning that the package does not exist. This is the default behavior without debuginfo-install, i.e. `dnf install foo` or `dnf install xorg-x11-server-xwayland`. Additional info: Fixing this issue would help detecting typos such as "xorg-x11-server-xwayland" instead of "xorg-x11-server-Xwayland".
I created a patch that should solve the issue (https://github.com/rpm-software-management/dnf-plugins-core/pull/243).
The issue is solved by dnf-plugins-core-3.0.1-1 that was released into rawhide.
