I ran into the same problem - but I noticed that I had two calls to the postperforminstall. The first one was a POST to the url
/install/api/PostPerformInstall/
That was being redirected to
/install/api/postperforminstall/ as a GET.
I have a redirect rule for SEO reasons, forcing all urls to be lowercase. So that was the culprit in my case. Disabling the rule and running the postperforminstall again was successfull.
I would recommend if you have not found a solution for your problem to check weather you have a similar rewrite rule in config or your setup somewhere.
Error upgrading Umbraco 8.1.3 to 8.2
HI, Trying to upgrade to Umbraco 8.2 from version 8.13. We are getting the following error:
The requested resource does not support http method 'GET'.
This is from the url: /install/api/PostPerformInstall/ The above is from the browser developer tools.
The Umbraco screen reads:
Error during installation See the log for full details (logs can typically be found in the App_Data\Logs folder).
But the log file does not give any clue as to what is happening.
Has anyone come across this who can shed some light on what to look for please?
Thank you,
Pete

Hope this helps, have a nice day!
We commented out the rewrite rules in the config file and it upgraded successfully.
Hi, Yes that worked, thank you. We also had permissions missing in the media and umbraco folders for users
