Can't find error logs

[GlennvG]

I'm running Sitecore in a PaaS environment on Azure.

The installation of my package says it failed in the .json result file.

having the issue that when an package failed I get the reference to: d:\local\temp\__Upgrade\Upgrade_20180319T143205671

And not in my website folder. But the file in D:\local does not exist.
How can I change this folder?

That location is calculated by Sitecore, and is stored in the variable installationHistoryRoot in the InstallPackage class. I'm not sure how Sitecore calculates this location, and it may vary from version to version. The value is returned by the UpdateHelper.Install() method. I would take a look in that method to see how it is calculated in the version of Sitecore you are using.
