EXTREMELY IMPORTANT: Please attach a ZIP file containing your Akeeba Backup log file in order for us to help you with any backup or restoration issue. If the file is over 10MiB, please upload it on your server and post a link to it.



we are in the process to migrate our current Joomla3 site to Joomla4 and have created a test site. So far everything is working fine. 

We have frequqently updated the Akeeba Backup Professional and did not have any issues but starting now.

We cannot upgrade from Akeeba Backup Professional for Joomla! 4 version 9.6.0 to 9.6.1 and it is always failing with:

Error: Package installation

Copy file failed Paket Update: Bei der Installation der Erweiterung trat ein Fehler auf:   Independent from this error we had a warning on our Joomla site with regard to missing tmp directory for xml files and have added upload_tmp_dir='../tmp' to our PHP and the Joomla warning dissappeared. But still we cannot install version 9.6 1   We do not have any issues to installing other components, modules and plugins.     Best regards Markus Berwing

It's not a problem with our package, either. I always test before release that it can be installed afresh (new installation) and as an upgrade. I just tested the upgrade again right now on a new site; it works. Beyond that, I can see that thousands of sites already downloaded and installed the update without a problem.

The “Copy file” error comes from Joomla and it means that it could not copy a file. Which file? It won't tell you. At which point? It won't tell you. I have reported this as a problem years ago and it was fixed, but a later change in the code brought us back to where we started: useless error messages.

All I can do is point you to and I suspect that your Joomla temporary directory may not be writeable, something else may be emptying it, or one of the folders where Joomla installs Akeeba Backup is not writeable by the effective PHP user.
