Tried to install python3-dev and libssl-dev on a new Ubuntu 18.04 with:
$ sudo apt install libssl-dev python3-dev
But i get the following Error:
Reading package lists... Done

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:
libssl-dev : Depends: libssl1.1 (= 1.1.0g-2ubuntu4) but 1.1.1-1ubuntu2.1~18.04.4 is to be installed
Recommends: libssl-doc but it is not going to be installed
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.
What could cause this issue, and how to fix it?
cat /etc/apt/sources.list && cat /etc/apt/sources.list.d/*list. Maybe you have some version mixup? – Claudio Kuenzler Apr 21 '20 at 10:06
