Hi everyone, I followed the command step by step in this calculix page([Get the CalculiX adapter | preCICE - The Coupling Library](https://precice.org/adapter-calculix-get-adapter.html)) when I entered the command sudo apt install ./calculix-precice2\_2.20.0-1\_amd64\_jammy.deb It threw an error message like this: Reading package lists… Done Building dependency tree… Done Reading state information… Done Note, selecting ‘calculix-precice2’ instead of ‘./calculix-precice2\_2.20.0-1\_amd64\_jammy.deb’ Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: calculix-precice2 : Depends: libyaml-cpp0.6 (\>= 0.6.2) but it is not installable E: Unable to correct problems, you have held broken packages. But I already installed yaml-cpp, when I entered the command ```plaintext sudo apt install libarpack2-dev libspooles-dev libyaml-cpp-dev ``` the output is below Reading package lists… Done Building dependency tree… Done Reading state information… Done libyaml-cpp-dev is already the newest version (0.7.0+dfsg-8build1). libarpack2-dev is already the newest version (3.8.0-1). libspooles-dev is already the newest version (2.2-14). The following packages were automatically installed and are no longer required: libllvm13 libnotify4 Use ‘sudo apt autoremove’ to remove them. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. what’s wrong with it? ---

Hi there, This was a bug in debian package dependency description which is fixed now. I replaced the faulty jammy packages on the github release page of the calculix adapter. ---
