Sorry my copy and paste error.
cat /etc/apt/sources.list.d/astroberry.list
deb www.astroberry.io/repo/ bullseye main

sorry missed out the https://

It is not my copy and paste as it just did the same thing again.
I think the problem with my posiing the repo file is that the indi forum thinks I am writing a web page and automatically
strips off the https:// from the url. in the repo description after I post it .
Add a https a : and a // before the www.
Look at astroberry wiki page under Inslallation and replace buster with bullseye.

hello
then, indeed it works better with the https:// !
now i will follow the installation method of allsky
but it's normal that the command
libcamera-still -n -o test.jpg
doesn't work with my asi120 usb camera ?

hello
so I have an error during the installation,,

libcamera-still is only for raspberry pi cameras (attached direct to the board). These are not indi compatible (yet).
You have a USB astro camera which uses indi drivers.

Yes

For the $DBUS_SESSION_BUS_ADDRESS and $XDG_RUNTIME_DIR errors, you probably just need to reboot.

That's a question for Aaron Morris. You wont be able to start anything if the compilation failed.
Use an official pi power supply or get a better usb power supply/cable.

For the pyindi-client compile failure, ensure that INDI 1.9.7 is selected if you are using the Astroberry repos. You can manually rebuild pyindi-client using ./misc/rebuild_pyindi-client.sh

Hello Aaron
so I did what you said,
But I still have the following error

meteo@raspberrypi:~ $ systemctl --user start indiserver
Failed to start indiserver.service: Unit indiserver.service not found.
meteo@raspberrypi:~ $

what should I do

Chris

The other error is now gone, so that is good.

The setup.sh script has not yet completed, re-run that script again until it fully completes.
