    Installing libgtk-3-dev seems to break Ubuntu 12.04 interface

    Hi,

    I have a 64 bit HP NC6400 laptop. I develop applications using GTK+.

    Up to now, I've been using libgtk2.0-dev on Ubuntu 10.04, however I decided to get up-to-date so I installed 12.04 (complete fresh install). It looks good, but I ran into trouble as follows:

    After fresh install of 12.04, I did the following (and nothing else):

    sudo apt-get update
    sudo apt-get install aptitude
    sudo aptitude install libgtk-3-dev

    When libgtk-3-dev was preparing to install, I answered "Y" to both questions. Then I restarted.

    I type in my credentials at the graphical login screen, it accepts them, but then the screen goes black for a split second, and then returns to the login screen. If I try to move the mouse, it sticks and skips.

    I can type cntl-alt-f1 to go to TTY session and login just fine.

    I've tried doing:

    sudo aptitude remove libgtk-3-dev

    but that didn't help.

    I've attached the contents of .xsession-errors before I installed libgtk-3-dev, and then after I installed it and the trouble began. Don't know what I'm looking at.

    I couldn't attach the installation dialog (it's too big) so I've put it on my web site here:

    http://www.pdbuchan.com/libgtk-install.txt

    Advice?

    You made a couple of mistakes here -
    first you posted in wrong sub-forum for your issue.

    The real mistake is you accepted what aptitude wanted to do which basically removed anything to log in to.

    Next time it's is worth reading thru what is to be removed..., personally on a fresh install I'd update/upgrade first, then install add. packages & I wouldn't use aptitude for normal update/upgrade tasks

    Why not use aptitude? I thought it was like apt-get but kept better records of dependencies, so less likely to corrupt if you did an uninstall. Is that not right? I should use apt-get install instead?

    I did see a lot of stuff being removed, so I was suspicious, for sure, but I thought the install would stop dead if I said "no" to either of the "Accept?" queries.

    Can you expand a bit on what you said?

    Re: Installing libgtk-3-dev seems to break Ubuntu 12.04 interface

    I'd use apt-get because it would have upgraded your libgtk3* packages rather than what aptitude First suggested doing.
    That doesn't mean you had to accept aptitudes 1st. 'solution', you could have resolved it yourself or tried more aptitude solutions
    (or used apt-get.

    Ex.on a live 12.04 session right now, duped what you did. Aptitude handles the request 'wrong' as seen below - clipped, but exactly what you saw
    $ sudo aptitude install libgtk-3-dev
    clipped
    The following packages will be upgraded:
    gir1.2-gtk-3.0 gir1.2-pango-1.0 libcairo-gobject2 libcairo2 libglib2.0-0 libglib2.0-bin libgtk-3-0
    libgtk-3-common libpango1.0-0

    2nd aptitude solution -
    The following actions will resolve these dependencies:

    Upgrade the following packages:
    1) libgail-3-0 [3.4.1-0ubuntu1 (now, precise) -> 3.4.2-0ubuntu0.4 (precise-updates)]
    2) libgtk-3-bin [3.4.1-0ubuntu1 (now, precise) -> 3.4.2-0ubuntu0.4 (precise-updates)]
    Accept this solution? [Y/n/q/?]
    That would have likely not removed anything...

    On the other hand apt-get does it correct the 1st. time -
    sudo apt-get install libgtk-3-dev

    Re: Installing libgtk-3-dev seems to break Ubuntu 12.04 interface

    Sorry I took so long to get back.

    Anyway, I wanted to test this properly so I did a fresh OS install and then did

    apt-get update
    apt-get install aptitude
    aptitude install libgtk-3-dev

    But now, having learned that I can reject aptitude's initial offer of solution, I said "no" and let it offer a solution which involved upgrading those apps in need of upgrading, but with NO removals.

    Worked like a charm!

    Thanks for taking the time to provide the great answer!

    As you said, it might be wise to do an initial upgrade before installing anything anyway.

    Thanks again!

    Dave
