Unable to locate package realsense2_camera for Foxy

edit

Could you check whether you're running into #q379190?

A sudo apt update should error with a key expired problem.

I had this issue also earlier on the day, but it shoudl be solved now, sudo apt(-get) update is working. And I think, that these problems are not related to each other.

When I type sudo apt-get install ros-foxy-realsense and press tab button twice, I get the list of the following available packages:

ros-foxy-realsense2-camera-msgs
ros-foxy-realsense2-camera-msgs-dbgsym
ros-foxy-realsense2-description
ros-foxy-realsense-msgs
ros-foxy-realsense-msgs-dbgsym
