How to solve this seemingly impossible dependency problem?

ayatana · 02-13-2017, 12:49 PM

I cannot install any new packages using apt. When I try to install anything I get error like this,

Code:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libstdc++6 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.4) but it is not installable
              Breaks: fceux (<= 2.2.2+dfsg0-1) but 2.2.1+dfsg0-2 is to be installed
              Breaks: libstdc++6:i386 (!= 5.4.0-6ubuntu1~16.04.4) but 6.2.0-3ubuntu11~14.04 is to be installed
 libstdc++6:i386 : Breaks: libstdc++6 (!= 6.2.0-3ubuntu11~14.04) but 5.4.0-6ubuntu1~16.04.4 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Now when I run

Code:

sudo apt-get install -f

I get this error,

Code:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Correcting dependencies... failed.
The following packages have unmet dependencies:
 libstdc++6 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.4) but it is not installable
              Breaks: fceux (<= 2.2.2+dfsg0-1) but 2.2.1+dfsg0-2 is installed
              Breaks: libstdc++6:i386 (!= 5.4.0-6ubuntu1~16.04.4) but 6.2.0-3ubuntu11~14.04 is installed
 libstdc++6:i386 : Breaks: libstdc++6 (!= 6.2.0-3ubuntu11~14.04) but 5.4.0-6ubuntu1~16.04.4 is installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies

When I try to see any held packages with

Code:

sudo apt-mark showhold

The terminal spits out nothing. I thought that probably libstdc++6 is being held, so tried to unhold it using

Code:

sudo apt-mark unhold libstdc++6

It seems like it wasn't held. The output was,

Code:

libstdc++6 was already not hold.

When I try to sudo apt-get autoremove, I get this extra error along with the ones above,

Code:

W: Ignoring Provides line with DepCompareOp for package libreoffice-l10n

And I have tried the following commands with no result at all,

Code:

sudo apt-get clean
sudo apt-get autoclean
sudo dpkg --configure -a

This whole thing started when I tried to install libstdc++6 from Ubuntu's higher (than the version that I am running) version repository. I have forced to dpkg to to remove it and probably that put me deeper in the quicksand. Now, I have run out of my bag of tricks here. Please help.

Do you have a recent backed up/imaged copy of your system that you can revert to? That would be my first choice if faced with this scenario.

In general, so much of the system is dependent on the correct versions of packages like libstdc++ that it's best to leave these well alone. If not, you should definitely back up your system before playing about with them.

If you don't have a system backup to which you can revert, the first thing I would suggest is that you look closely at /var/log/apt/history.log and term.log to see exactly which commands you have issued and which packages have been added/removed since you tried installing libstdc++6 from the "higher version" repository.

You will need to tell us about this "higher version" repository. Generally, you should not install packages from any repository that represents a different system version to the one you're using - it often leads to trouble, particularly if you're talking about system libraries.

Have you tried

Code:

dpkg-reconfigure -a

? Note that this is different than

Code:

dpkg --configure -a

From man dpkg

Code:

   --configure package...|-a|--pending
          Configure a package which has been unpacked but not yet  config‐
          ured.   If  -a  or  --pending  is  given instead of package, all
          unpacked but unconfigured packages are configured.

          Configuring consists of the following steps:

          1.  Unpack  the  conffiles, and at the same time back up the old
          conffiles, so that they can be restored if something goes wrong.

          2. Run postinst script, if provided by the package.

From man dpkg-reconfigure

Code:

dpkg-reconfigure - reconfigure an already installed package

   -pvalue, --priority=value
       Specify the minimum priority of question that will be displayed.
       dpkg-reconfigure normally shows low priority questions no matter
       what your default priority is. See debconf(7) for a list.

   -a, --all
       Reconfigure all installed packages that use debconf. Warning: this
       may take a long time.

What's your sources.list & sources.list.d look like? One thing I have recently done when I upgraded some packages to experimental is create a /etc/apt/preferences.d/<whatever> file and set the system priority to 1100 for the regular package. This high a priority will actually allow apt to DOWNGRADE packages if it's required in order to install the target software.

Unfortunately, I don't have a backup.

I am on Ubuntu 14.04 LTS with support till 2019. But I downloaded the package from Ubuntu 16.04 LTS repository.

I will look at the log history but as apt and dpkg complain, the problem is with libstdc++6 package and there is nothing I can do about it. I cannot install, remove or reinstall any packages due to dependency problem in the way. I think I have completely broken my packages system.

Not necessarily. You can place packages which may cause dependency problems on hold and concentrate on addressing individual packages one at a time. First, though, you should paste the relevant tail of history.log here so that we can what you've done since (and including) you updated libstdc++6.

Also, as noted by another poster, list your current repos here (if you have inxi installed, inxi -r provides a handy of listing of these).

I don't have inxi installed and I obviously cannot install it. But I have cat'd my /etc/apt/sources.list.

Try

Code:

dpkg --purge ca-certificates

Then try

Code:

dpkg-reconfigure -a

again

God. I am in a heap of trouble now. I force purged the certificates, reconfigured dpkg and now when I run apt-get install -f, I get more dependency problem than I began with,

Try to apt install ca-certificates without any other packages. And I would temporarily edit your apt.sources to only include Ubuntu official repositories for the moment

That's because dpkg --purge removed both the ca-certificates package and its config files, not just the latter.

apt-get download ca-certificates will download the deb to the folder where you run the command, and then you can try installing the deb by dpkg -i or double-clicking on it. That's assuming that its dependencies are met - if not, you will have to download those as well.

Well, you never want to do that.

Re-install, is the most direct route.

I would try setting up pinning with priority >1000 like I had suggested and install with a target (-t repo). This allows apt to downgrade packages installed from newer repos to the version in the target. I have used it successfully several times to fix exactly this. It's not 100% successful, but it's very good.
