I want to update from 2018.2.13 to 2018.5.22 on php 7.1 debian 8.10. I am able to download and to start the update, but it freez. I can see that it is unable to unzip the files from update.zip to unzipped.zip. If I try to go manually, there is update.php inside an if I start it I become an error.
Can you help me?
