Hi,
it seems as if curl is installed:

pi@raspberrypi:~ $ curl -V
curl 7.74.0 (arm-unknown-linux-gnueabihf) libcurl/7.74.0 OpenSSL/1.1.1n zlib/1.2.11 brotli/1.0.9 libidn2/2.3.0 libpsl/0.21.0 (+libidn2/2.3.0) libssh2/1.9.0 nghttp2/1.43.0 librtmp/2.3

Are there any other tests I can do?

@homoran
I don't know from my mind but is this important for this issue?
I thought it is a more general problem instead of related to any specific base.

Hi yesterday I did the upgrade von buster to bullseye.

Hi this is the syntax I have tried but nothing is happening during execution.
No error, no warning nothing.

Hello,
I wanted to install iobroker on my Raspberry debian 11.
In the installation guidelines there is always mentioned a syntax starting with curl.
Unfortunately nothing happens while executing this. It means after 2 sec the input line is appearing again.

Does anyone has a hint for me what the problem could be?
Is there a different why to install iobroker?

Thanks in advance.

Regards
Christian
