DirectAdmin cannot be installed in Debian version 11.2

[calmok]

I currently use the Debian version 11.2 official website to download the pure system
I follow https://docs.directadmin.com/getting-started/installation/installguide.html
This operation cannot be completed because DirectAdmin is installed.
Do any friends have the same problem。

This operation cannot be completed because DirectAdmin is installed.

What do you mean with this? This doesn't make much sense to me. What exact error messages do you get?

I installed DirectAdmin over the last few months multiple times on Debian 11 and it always worked beside the fact that cURL is missing and thus the pre-installation step for Debian is incomplete. Beside of that, it still worked so it seems cURL is installed by DirectAdmin itself in case it is missing.
