Установлен python2.7.16 из источника, но не может его увидеть

Я пытался обновить свой python с 2.7.x до 2.7.16 и закончил тем, что полностью вручную удалил python и установил его из исходного кода, поскольку у меня возникли проблемы. Теперь я хочу установить python-pip (из apt), но apt, похоже, не понимает, что python установлен, и хочет установить (старую версию) поверх моей.

    ubuntu@ubuntu:~/$ dpkg --configure
dpkg: error: --configure needs at least one package name argument

Type dpkg --help for help about installing and deinstalling packages [*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;

Options marked [*] produce a lot of output - pipe it through 'less' or 'more' !

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 python-pip : Depends: python:any (< 2.8)
              Depends: python:any (>= 2.7.5-5~)
              Recommends: python-all-dev (>= 2.6) but it is not going to be installed
              Recommends: python-setuptools but it is not going to be installed
 python-pkg-resources : Depends: python:any (< 2.8)
                        Depends: python:any (>= 2.7.5-5~)
 python-wheel : Depends: python:any (< 2.8)
                Depends: python:any (>= 2.7.5-5~)
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
