ros-melodic-costmap-2d dependancy error

I got the follwing error when doing sudo apt upgrade
system: ubuntu18.04 ros melodic

The following packages have unmet dependencies:
 ros-melodic-costmap-2d : Depends: ros-Melodic-message-filters but it is not installable

I guess there is a typo in the dependancy? Where ros-Melodic-message-filters has a capital "M"

commented

I don't see how that could have happened - A) we haven't had a release in a while, and B) the "ros-melodic-" part gets added by bloom (so it is automated when we do the release)

commented

I also confused how this could happen. So I also asked in rosdistro package.

So.. I just downloaded http://packages.ros.org/ros/ubuntu/pool/main/r/ros-melodic-costmap-2d/ros-melodic-costmap-2d_1.16.7-1bionic.20210921.222823_amd64.deb and extracted the control file:

Package: ros-melodic-costmap-2d

Section: misc
Priority: optional
Homepage: http://wiki.ros.org/costmap_2d
Description: This package provides an implementation of a 2D costmap that takes in sensor data from the world, builds a 2D or 3D occupancy grid of the data (depending on whether a voxel based implementation is used), and inflates costs in a 2D costmap based on the occupancy grid and a user specified inflation radius.
 This package also provides support for map_server based initialization of a costmap, rolling window based costmaps, and parameter based subscription to and configuration of sensor topics.

I don't see any problem here

Just run upgrade again, the error dispears. Seems someone fixed it silently?
It was broken this morning, but fixed this afternoon...

It sounds like you might have gotten an inconsistent state in your apt-update. As it's working and there's nothing to track to follow up I'm going to close this.
