Upgrading from 16 to 18 (updated info)

Hello,
thank you for this great tool.

Though, I ran into a problem.

When updating my instance of Nextcloud 16.0.3 to 16.0.9 I click on “Auto Update” and stops at the “create backup” point. It sais “Parsing response failed.” Any idea on how to solve this?

I tried the manual upgrade described here: https://docs.nextcloud.com/server/16/admin_manual/maintenance/manual_upgrade.html

this worked on 1 instance of nextcloud. When done, I wanted to install V18 in order to be up to date. the sam eprocess didn’t work.

The problem though it: I have no idea about linux and therefore I have problems using putty and the ssh access to the webspace, and therefore I can not run the update command. on version 17 it worked and I didn’t had an upgrade screen after entering the domain.

Anyone any idea?

thank you
