Solved Can not uninstall Nextcloud

[privsec]

When I attempt to uninstall nextcloud, I get an error message

In my logs, I get

I have restarted the service for nextcloud and reattempted the uninstall, but it did the same thing

@privsec Can you check the output of journalctl -u nginx ? It seems nginx is not reloading for some reason. You can also try systemctl reload nginx manually to see if it works (it most likely won't). Do you happen to have any custom nginx configs by any chance?

@girish Thanks for the reply, I am not sure where to run those commands. And no, I do not.

To add to this, I just tried to install another version of nextcloud and it wont let me do that either.

@privsec said in Can not uninstall Nextcloud:

I am not sure where to run those commands

These are to be run directly on the Cloudron host via for example ssh.

@privsec Did you manage to run the commands?

@girish

I just did now, here is the first

username@VPSID:~$ journalctl -u nginx
Hint: You are currently not seeing messages from other users and the system.
      Users in groups 'adm', 'systemd-journal' can see all messages.
      Pass -q to turn off this notice.

username@VPSID:~$

The second one is

username@VPSID:~$ systemctl reload nginx

nginx configs became corrupt. Once we got nginx up, it uninstalled. I am putting notes on why nginx configs were corrupt at https://forum.cloudron.io/topic/5457/site-is-not-reachable
