As with other posts in this stack exchange, I’m having issues with installing python3-dev on a fresh install of Ubuntu (18.04) that is running a pre-installed python3 (3.6.9-1~18.04). Many of the recommended fixes in those posts that I have tried have worked, such as uninstalling and reinstalling python3. I’ve had to restore my laptop to the factory defaults twice now because apt ended up breaking much of the operating system by modifying python3. Aptitude also could not resolve the conflicts.
More specifically, when I attempt to do
sudo apt install python3-dev I get the following:
Reading package lists... Done Building dependency tree Reading state information... Done 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: python3-dev : Depends: python3 (= 3.6.5-3) but 3.6.7-1~18.04 is to be installed Depends: libpython3-dev (= 3.6.5-3) but it is not going to be installed Depends: python3.6-dev (>= 3.6.5-2~) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
Here is the output of running
sudo apt update:

and the output for
sudo apt upgrade:
Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
I’d appreciate any help in figuring out how I can resolve these issues. Upgrading to the latest version of Ubuntu (20.04) is not an option right now.
