- # 47948
What happened?
I can't execute the installation script for components or packages. This results in not executed install-steps, migrations and more.
pkg_foobar_5_8_0-a1_QUICKBUILD.zip
Version
6.1-dev (2026-06-13)
Expected result
The installation script is executed.
Actual result
The installation script is not executed. In my example, resulting in an error page.
System Information
I'm using the latest dev version of Joomla 6.1
Additional Comments
I suspect the latest change here: https://github.com/joomla/joomla-cms/blob/6.1-dev/libraries/src/Installer/InstallerAdapter.php#L950
After changing the path back to 'source', both the component and the package install scripts work.
For components/packages, the installation script is checked for existence but copied after this check. Looks like a chicken-egg issue here.

I investigated this locally and the issue appears to be related to the changes introduced in #47637.
For components and packages, the installer script file is checked for existence before it has actually been copied to its final location. As a result, the install script (install, update, migrations, etc.) is never executed.
Changing the path back to 'source' in InstallerAdapter.php restores the previous behaviour and allows the installation scripts to run correctly.
This looks like a regression caused by the order of operations (script existence check happening before the copy step). It would be good to confirm whether the check should continue to use the original source path until the package files have been moved into place.
I'll try to prepare a reproducer and possible fix if needed.
Thanks @svenbluege , you saved us a lot of headache with the early test.
