I clicked on "Install" on Cockpit's Applications page, which according to `pkcon get-transactions` installed the following:

 - installing python3-zipp-0.5.1-2.fc31.noarch
 - installing python3-importlib-metadata-0.23-1.fc31.noarch
 - installing python3-pluggy-0.12.0-2.fc31.noarch
 - installing python3-wcwidth-0.1.7-11.fc31.noarch
 - installing python3-py-1.8.0-2.fc31.noarch
 - installing python3-packaging-19.0-2.fc31.noarch
 - installing python3-more-itertools-7.2.0-1.fc31.noarch
 - installing python3-attrs-19.1.0-2.fc31.noarch
 - installing python3-atomicwrites-1.3.0-2.fc31.noarch
 - installing python3-pytest-4.6.9-1.fc31.noarch
 - installing python3-argparse-manpage-1.2.2-1.fc31.noarch
 - installing bash-completion-1:2.8-7.fc31.noarch
 - installing python3-lib389-1.4.2.5-3.fc31.noarch
 - installing cockpit-389-ds-1.4.2.5-3.fc31.noarch

So the package name seems to match, cockpit-389-ds is installed and /usr/share/metainfo/389-console/org.port389.cockpit_console.metainfo.xml is present. It also ships an apparently correct /usr/share/cockpit/389-console/manifest.json , I see "389 Directory Server" in the menu, and at least its initial screen works.

Reloading the page, and even restarting cockpit and packagekit doesn't help, so it's not just a bug with not picking up dynamic updates in the page.

OTOH this works correctly for subscription manager and cockpit-podman.

Marius, do you see what could be wrong here?

This message is a reminder that Fedora 31 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '31'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 31 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 31 changed to end-of-life (EOL) status on 2020-11-24. Fedora 31 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Problem persists, Fedora 38.
