    Problem upgrading python-newt

    Hello all!

    KPackageKit reported that I had some updates, so I hit install all. There was an error, so I tried apt-get. His is the result:
    Code:
    Preparing to replace python-newt 0.52.2-11.3ubuntu3 (using .../python-newt_0.52.2-11.3ubuntu3.1_amd64.deb) ...

    E: Sub-process /usr/bin/dpkg returned an error code (1)
    I googled this error and came up empty.

    Thank's for your help!

    Hi

    I would start by doing

    Code:
    sudo apt-get update 
    sudo apt-get dist-upgrade
    And see the output, is that what you ran? It seems as if a post-removal script is failing. We may need to do some sort of minor surgery

      Hello lmilano! Thank you for your reply.

      This is the output from apt-get dist-upgrade:
      Code:
      You might want to run `apt-get -f install' to correct these.
      The following packages have unmet dependencies:
       python-newt: Depends: libnewt0.52 (= 0.52.2-11.3ubuntu3) but 0.52.2-11.3ubuntu3.1 is installed
      E: Unmet dependencies. Try using -f.
      and this is the output from apt-get -f install:
      Code:

      What now?

        Let's try this (I am looking at man:dpkg in konqueror

        Code:
        dpkg --remove-reinstreq -r python-newt
        Also: If you have synaptic installed, you can find broken packages and many times fix them from there very easily. If not, I would recommend installing it whenever we fix your system

          As Jaunty is still still in alpha stage, and as is the case with any alpha stage OS, one can expect frequent breakage. But if one waits 24-hours and dist-upgrades again, most, if not all breakages get fixed. This 'wait and see' approach is safer than attempting to force a solution.

            Mmmmm. You mean Karmic? I think this is in Jaunty (9.04) really!

                  A package is attempting to remove a package that you appear not to have installed - python-newt. One could attempt to 'satisfy' this poorly written packaging script by installing what it wants to remove. Open a console and type:
                  Code:
                  sudo apt-get install --simulate python-newt
                  If apt doesn't report anything out of the ordinary, then repeat without the --simulate option. When done, procede with the apt-get -f install.

                      Well, it was early here, too, how about (please see the manpage as I indicated above for more)

                      Code:
                      sudo dpkg -r --force-all python-newt
                      sudo apt-get install python-newt

                        Re: Problem upgrading python-newt

                        So there is some vestige left over on your system that points to this package - python-newt - that it expects to find, but can't, because it isn't (or never was).

                        Try the following:
                        Code:
                        sudo apt-get install --reinstall python-newt

                          something potentially harmful. It should not be used except in very special situations. Using force-yes can
                          potentially destroy your system!

                            Just the one in JKaunty 9.04 plus updates:
                            --force-things, --no-force-things, --refuse-things
                            Force or refuse (no-force and refuse mean the same thing) to do some things. things is a comma separated list of things specified below. --force-help displays a message describing them. Things marked with (*) are forced by default.
                            Warning: These options are mostly intended to be used by experts only. Using them without fully understanding their effects may break your whole system.

                            all: Turns on (or off) all force options.
                            I did try these two commands on my system before posting, no issues whatsoever. But thanks for the heads up.

                              --reinstall didn't work. Same error.

                              @lmilano:
                              Code:

                              Was the correct command (I didn't now what man:dpkg was). But it didn't work.

                              Code:
                              sudo dpkg -r --force-all python-newt
