During deployment of the landscape-server charm, when using both install_sources and install_keys, the install_sources get added before the install_keys and apt update runs without the apt key making the update fail, which then makes the apt install of landscape-server fail because it doesn't know where to find the package.

Eventually this is retried by Juju and it works on further attempts because the apt key is now imported. However this causes the landscape-server unit to fail with an error in the workload status.
