A gcc compiler was misbehaving, and in the process of fixing it part of the libc6 package was uninstalled. Now I am trying to reinstall it using apt-get on Ubuntu 14.04 (3.13.0-24-generic). However, sudo apt-get install libc6-dev gives the following error message:

The following packages have unmet dependencies:
 libc6-dev : Depends: libc6 (= 2.19-10ubuntu2) but 2.19-10ubuntu2.1 is to be installed
E: Unable to correct problems, you have held broken packages.

I have tried using aptitude install, uninstalling various packages, and basically every variant of the command I can think of. However, they all give a variant of this error. How can I fix this, or at least work around this to install gcc and gfortran?

Edit:

Here is the output of apt-cache policy libc6 libc6-dev:

  • Please edit your question to include the output of apt-cache policy libc6 libc6-dev – steeldriver Jul 16 '18 at 20:35
  • Done. Let me know if there's any other information I can add. – JAustin Jul 17 '18 at 4:31

    Looks very strange. Why do you have mentions of utopic if you are running 14.04 LTS (trusty tahr)? Please add output of cat /etc/os-release and grep utopic -ir /etc/apt/sources.list /etc/apt/sources.list.d/*.list to the question. – N0rbert Jul 17 '18 at 10:28

    I am now very confused too. The kernel version is 3.13.0-24-generic (i.e. 14.04), but cat /etc/os-release shows that it is running 14.10. – JAustin Jul 17 '18 at 17:38
  • Can you post the result of sudo apt-get install libc6=2.19-10ubuntu2? I updated my answer... – Olimjon Jul 25 '18 at 13:41

OK, let's start everything from scratch:

You can do what recommends user @doug to solve your problem:

wget https://launchpad.net/~ubuntu-security/+archive/ubuntu/ppa/+build/6608877/+files/libc6-dev_2.19-10ubuntu2.1_amd64.deb
sudo dpkg -i libc6-dev_2.19-10ubuntu2.1_amd64.deb

If this works, you can upvote this answer, however, do not accept this. Wait until the original author posts the answer, then accept it.

But, keep in mind that by using this method you are only bypassing the real problem. You cannot update your repository, add PPAs or in worst case if something happens with your package cache, install other programs. So, I recommend you to use this method if nothing else helps.

In case if you truly want to cleanly solve the problem, then:

Step 1: Start cleaning the mess with sources.list:

Run the following command to remove PPAs other than official Ubuntu repository, as they became obsolete:

sudo rm /etc/apt/sources.list.d/*.list

Then backup, open and edit the sources.list:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.old
sudo gedit /etc/apt/sources.list

Remove everything from there and add these lines:

deb http://old-releases.ubuntu.com/ubuntu utopic main universe restricted multiverse
deb http://old-releases.ubuntu.com/ubuntu/ utopic-security main universe restricted multiverse
deb http://old-releases.ubuntu.com/ubuntu utopic-updates main universe restricted multiverse

Save and exit.

Step 2: Update the repository:

Run the following command:

sudo apt-get update

Ensure that this command works flawlessly. In case of GPG error happens, add keys and update your repository again:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192

Step 3: Fix ldconfig:

Run the following commands:

wget http://launchpadlibrarian.net/172657659/libc-bin_2.19-0ubuntu6_amd64.deb
dpkg -x libc-bin*.deb libdir/
sudo cp libdir/sbin/ldconfig /sbin/
sudo dpkg -i libc-bin*.deb
sudo apt-get install -f

Partly taken from here.

Step 4: Install:

Run the following commands:

sudo apt-get install libc6=2.19-10ubuntu2
sudo apt-get install libc6-dev

Hope this helps...

  • Don't do that! If you remove the glibc from a running system, you will break it. apt-get will stop working while removing the glibc. – Simon Sudler Jul 25 '18 at 8:42
  • @Simon Sudler, thanks. I edited the answer. I had no idea of libc6 was such an important package – Olimjon Jul 25 '18 at 8:47
  • It will still break the system. Try removing the libc6 in a docker container and watch the fallout. There is also a message from apt-get: WARNING: The following essential packages will be removed. – Simon Sudler Jul 25 '18 at 8:53
  • @Simon Sudler, well, it worked for me without any removals on my own system Ubuntu 18.04. If you want I will include this as a proof. – Olimjon Jul 25 '18 at 8:57
  • No, this is not a docker question, but if you want to test who to destroy your base system, docker contains are a save way to do it. Anyway, the reinstall will not fix the broken dependeny issue with the libc6-dev. It can be solved my manuall install the packages with dpkg -i -f. But before that, the apt sources must be fixed... and I am not willing to write a two page answer ;-) – Simon Sudler Jul 25 '18 at 10:43

have you tried just sudo apt install libc3-dev

also you can type sudo apt search libc3 and that shows me 2 packages

    libc3 is a completely different library that is not related to and has nothing to do with libc6 which is what the asker is having issues with. libc6 is the standard C libraries. That is a critical component to a ton of software (and libraries and compilers). (The post you've made doesn't have anything to do with the original question or issue that was posted by the asker of this question) – Thomas Ward Jul 16 '18 at 22:17
