=CentOS 8.x dnf verify installed packages=

To verify all installed packages use:
<pre>
  rpm --verify -a
</pre>

Note that this does not checks for missing dependencies.  For that use:
<pre>
  yum check dependencies
</pre>
which finds issues with dependencies of installed programs.

On CentOS 8 this shows:
<pre>
  Modular dependency problems:

 Problem 1: conflicting requests
  - nothing provides module(perl:5.26) needed by module perl-DBD-MySQL:4.046:8010020191114030811:073fa5fe-0.x86_64
 Problem 2: conflicting requests
  - nothing provides module(perl:5.26) needed by module perl-DBD-SQLite:1.58:8010020191114033549:073fa5fe-0.x86_64
 Problem 3: conflicting requests
  - nothing provides module(perl:5.26) needed by module perl-DBI:1.641:8010020191113222731:16b3ab4d-0.x86_64
</pre>

Unfortunately dnf works better on CentOS 8 then yum and hence '<tt> yum check dependencies</tt>' does not helps and results in output similar to:
<pre>

Package perl-4:5.26.3-416.el8.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!  
<pre>


However with dnf we can do:
<pre>
  dnf module list perl
</pre>
which results into
<pre>

Then use:
<pre>
dnf module -y install perl:5.26
</pre>
which shows output
