Package installation failing

Hi I have a raspberry pi with Debian 12 installed which I am trying to setup to use the simtrace2 hardware. I am having difficulty installing the simtrace2-util package – even though I believe I have followed the installation instructions (https://osmocom.org/projects/cellular-infrastructure/wiki/Nightly_Builds) I can see the repo in the sources list following the provided instructions: steven@simtrace:~$ cat /etc/apt/sources.list.d/osmocom-nightly.list deb [signed-by=/etc/apt/trusted.gpg.d/osmocom-nightly.asc] https://downloads.osmocom.org/packages/osmocom:/nightly/Debian_12/ ./ If I apt list – I can see the package steven@simtrace:~$ sudo apt list simtrace2-utils [sudo] password for steven: Listing...
