Fehler beim Start des Contao Managers

[Andi-cto]

_Edit: Das beschriebene Problem konnte ich mindestens fünfmal reproduzieren. Beim sechsten Mal ist es nicht mehr aufgetreten.

Fehlermeldung beim Starten des Contao Managers:

System Recovery The Contao Manager detected files that look like Contao, but the Command Line Interface does not work as expected. Please choose an option to repair your installation. Automatic Repair (…)

Beim Ausführen der Automatic Repair dann folgende Fehlermeldung:

Installing Composer Dependencies Console task terminated! The background task has stopped unexpectedly. Please check the console protocol.

Ok-Button ausgegraut (“wheel” bzw. lässt sich nicht drücken; siehe Screenshot)

Hier das Protokoll:

This may cause invalid reports of corrupted archives. Besides, any UNIX permissions (e.g. executable) defined in the archives will be lost.
Installing 'unzip' may remediate them.

Kannst du noch erwähnen warum du das Ticket geschlossen hast?

We have faced the same problem with v4.9.2 problem after a zip example extension was uploaded. The console interface gives us nothing about what was going on and also we have no found any logs on var/logs/prod-...

How can we debug it? Because we really don't know what is failing.
