Could someone tell me where im going wrong? I want to install openssl-devel for "Cern ROOT".

Does this answer your question? How do I resolve unmet dependencies after adding a PPA? — Artur Meinild, Feb 19 '21 at 10:09
Did you try the suggested command sudo apt --fix-broken install? Or remove the package debhelper and reinstall the latest official version? — Artur Meinild, Feb 19 '21 at 10:10

You are trying to install a version of libssl-dev that requires a very old version of cmake. You might want to check if this is really the version of libssl-dev that you want or need. If it only builds with a cmake version that old, chances are it's a very old and unmaintained version. Especially with security software like libssl that's probably not a good idea.
