Description Pat Riehecky 2016-11-17 17:24:53 UTC 
Description of problem:
When using DNF to determine if a "package" is installed doesn't consider any RPM provides.  This can lead to some odd behavior in config management tools as well as user actions.

Version-Release number of selected component (if applicable):dnf-2.0.0-0.rc1.4.fc26


How reproducible:100%


Steps to Reproduce:
1. Install Fedora
2. rpm -q --provides systemd (should provide 'syslog')
3. dnf list installed syslog (shows not installed)
4. dnf install syslog (result is 'Nothing to do.')

Actual results:
[root@fdeebbd6f397 /]# dnf list installed syslog
Last metadata expiration check: 0:05:39 ago on Thu Nov 17 17:18:26 2016.
Error: No matching Packages to list
[root@fdeebbd6f397 /]# dnf install syslog
Last metadata expiration check: 0:05:43 ago on Thu Nov 17 17:18:26 2016.

Expected results:
'dnf list installed' should also consider RPM provides

Eek, heck no. Provides are provides and should remain hidden unless specifically asked for, just like with rpm and yum and...

Dnf could be more informative than the rather terrible "nothing to do" message however, it could explain WHY, eg:

"syslog is already installed (provided by systemd)"
Comment 2 Igor Gnatenko 2016-11-21 12:22:32 UTC 
actually we already print message:
$ sudo dnf install syslog
