Hello,

while cleaning up a long-running Joomla site (migrated over the years from Joomla 2.5 all the way to 5.4, with Admin Tools installed and kept up to date throughout), I found a leftover from what I believe is a very old Admin Tools release: the discontinued "Akeeba Version Check" system plugin (plg_system_akversioncheck).

The situation on my site was as follows:

The plugin folder plugins/system/akversioncheck/ still existed, containing the legacy (pre-namespace) plugin code.
The plugin was still registered and enabled in #__extensions, so it was being loaded on every request.
Its package_id still pointed to the current pkg_admintools package. Because of that, Joomla refused to uninstall it individually with the message that it is part of a package that does not allow uninstalling individual extensions. Uninstalling the package itself was obviously not an option, as that would have removed the current Admin Tools installation.
Workaround that solved it cleanly: UPDATE #__extensions SET package_id = 0 WHERE extension_id = ; — after that, a regular uninstall through the Extensions Manager worked and removed both the database entry and the folder.

Two related leftovers I also found in administrator/language/en-GB/, apparently from old Admin Tools versions: en-GB.plg_installer_admintools.ini / .sys.ini (no matching plugin folder exists under plugins/installer/ anymore) and en-GB.com_admintools.menu.ini.

Request: Could you consider adding a cleanup step to the Admin Tools package install/update script that removes the obsolete akversioncheck plugin (files and #__extensions row, or at least detaches it from pkg_admintools so users can uninstall it themselves), and deletes the orphaned language files listed above? Sites that have been upgraded across major Joomla versions for a decade are likely to carry these same leftovers without knowing it.

Thank you for your work on Admin Tools!

None of that is actually an issue caused by anything we do. Remember, we just provide an XML manifest for each extension.

The package's manifest list the extensions we include, nothing more and nothing less. Joomla is responsible for removing the leftovers.

Likewise, in the component's manifest we list the directories included in the frontend, backend, and api parts of the component. Joomla is responsible for removing the leftovers.

Look. Last time I tried reporting Joomla extension installation issues I was abused by certain core maintainers. The issues I was told are not real were later identified and fixed – except for one which is confirmed, but nobody has been able to fix (fair; I couldn't fix it either, and GOD, HAVE I TRIED). The abusive post is still up, no apology was offered, so I am not going to risk a repeat. I also know the moment I try to add something like what you described the abuse will return, uninvited and unprovoked. So, no, sorry, I am not doing that. I hope you understand.

These, and many other issues, I have observed on several sites. In fact, I have created an extension called Onthos which detects and fixes those issues. For stubbornly uninstallable extensions, like what you had, it offers a Forced Uninstallation feature which does the trick without database surgery. It's paid, for now – though very cheap, and even cheaper for you since you're an active subscriber to our other software.
