CentOS 8.x dnf verify installed packages

To verify all installed packages use:

  rpm --verify -a

Note that this does not checks for missing dependencies. For that use:

  yum check dependencies

which finds issues with dependencies of installed programs.

On CentOS 8 this shows:

  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

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

Package perl-4:5.26.3-416.el8.x86_64 is already installed.
Dependencies resolved.
Nothing to do.

<pre>


However with dnf we can do:
<pre>
  dnf module list perl

which results into

Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

Then use:

dnf module -y install perl:5.26

which shows output
