Cannot install catkin-tools on Debian buster due to Python version requirement

edit

I installed ROS Noetic on a Debian Buster system, which is listed as a supported platform.

However, I cannot install packages (like python3-catkin-tools) that depend on the python3-osrf-pycommon package because it requires Python 3.8, and Buster provides Python 3.7.

$ sudo apt install -s -o Debug::pkgDepCache::AutoInstall=true python3-catkin-tools

    python3-osrf-pycommon:amd64 Depends on python3:any:any < none @un H > (>= 3.8~) can't be satisfied!

Though python3-osrf-pycommon is listed on the package index as not being supported on Noetic...
