    QuestionQuestion

    I was struggling so much to install an application. And somewhere in comments someone had said I went brutal and did rm -rf /usr/lib/python2.7 and then I did the same. And after that I did sudo apt purge python2.7-minimal now my system is completely broken for example when I do sudo apt upgrade I get:

    The following packages have unmet dependencies:
     gimp : Depends: python:any (>= 2.6.6-7~)
     libboost-mpi-python1.58.0 : Depends: python (< 2.8) but it is not installed

    And when I issue sudo apt-get -f install I get:

    The following additional packages will be installed:

    Suggested packages:

    Accepted AnswerAnswer

    You can fix the issue if you have access to some ubuntu VPS that is working fine:

    apt download python2.7-minimal libpython2.7-stdlib python2.7
    

    Then you have to copy the essential files to your own system with:

    sudo scp you@yourserver:/usr/lib/python2.7/*.py /usr/lib/python2.7/
    sudo scp -r you@yourserver:/usr/lib/python2.7/plat-x86_64-linux-gnu /usr/lib/python2.7/
    sudo scp -r you@yourserver:/usr/lib/python2.7/logging /usr/lib/python2.7/
    sudo scp -r you@yourserver:/usr/lib/python2.7/encodings /usr/lib/python2.7/
    

    Then you should use dpkg for installing python:

    sudo dpkg -i python2.7-minimal_2.7.12-1ubuntu0~16.04.2_amd64.deb libpython2.7-stdlib_2.7.12-1ubuntu0~16.04.2_amd64.deb python2.7_2.7.12-1ubuntu0~16.04.2_amd64.deb
    

    Then you should let apt take care of everything itself:

    sudo apt-get install -f
    

    Then You can verify that apt is working fine with:

    sudo apt upgrade
