From 4.5.1 to 4.6.0 - Error 500: It's not an Installation package.

[Gery]

Hello,

For some reasons, I can't manage to upgrade from 4.5.1 to 4.6.0 as I keep getting this error:

[2017-08-04 07:01:12] Espo.ERROR: API [POST]:/:controller/action/:action, Params:Array ( [controller] => Admin [action] => uploadUpgradePackage ) , InputData: - It's not an Installation package. [] []
[2017-08-04 07:01:12] Espo.ERROR: Display Error: It's not an Installation package., Code: 500 URL: /my/api/v1/Admin/action/uploadUpgradePackage [] []

I don't know what to do in this case...

Hi Gery,

Maybe the packhe wasn't downloaded well. Are you able to unzip the package to check whether it's ok?

Hello Yurikuzn.

i've downloaded it 3 times and opened it and all seemed good. I don't know why it is not working though.

Hello
go /data/upload/upgrades, find the newest archive name, find the same named folder, check if manifest.json exists in folder

Hello Tanya,

The folder "upgrades" exists but is empty. There is no archive in it. Should I upload the upgrade files manually in it?

Check data/logs and permissions to /data/upload/upgrades, please.
No, you don't need to do it manually
