Anytime I attempt to install libpng12-0 with this command:

sudo apt-get install libpng12-0

I get this returned:

I have NO IDEA how to work around this. I do have libpng16-16 installed, but I don't see why that would cause an issue. I've tried everything from downloading the .deb manually and installing it to trying to symlink the libpng16-16 so to that location. All of it gave me no luck.

Anyone have any advice?

Further information: any attempt to symlink another .so into the path provided (/usr/lib/x86_64-linux-gnu/libpng12.so.0) results in the deletion of that symlink and the same error. The .so I was attempting to symlink as a fix, was libpng.so which is provided by libpng-dev (or libpng16-16).

  • Try sudo rm /var/cache/apt/archives/libpng12-0_1.2.50-2+deb8u2_amd64.deb, and then rerun apt. Commented Dec 21, 2016 at 2:14
  • I've tried this and apt-get clean multiple times, in addition to grabbing the .deb directly off of the deb packaging site. Did it again, still no go, same error. Commented Dec 21, 2016 at 2:17
  • You could potentially grab the source and build it. I'd suggest 1.2.56 (at a minimum), there is a list of vulnerabilities in earlier versions here. Commented Dec 21, 2016 at 2:21
  • I think I'm going to give this another few days, or until I DIRELY need it, and then just build from source. This is driving me nuts and I can't even figure out what file or directory is missing during the unpack... Commented Dec 21, 2016 at 2:27
  • Can you post the output of ls -l /usr/lib/x86_64-linux-gnu/libpng12.so.0? It's likely that the symlink there is broken, and that you need to manually fix it. Commented Dec 21, 2016 at 9:52

I have this resolved now. I went to the Debian forums and asked my question here, where a helpful member pointed out that libpng12-0 isn't available for Stretch (should have specified my OS version earlier, sorry). I was trying to install the Jessie version, and that just... doesn't work with Stretch right now. There's a version of libpng12-0 in Sid, currently. It should make it's way to Stretch in the near future to solve this issue.

In the meantime, I abandoned installing the Jessie libpng12-0 package, and just did the Wheezy package, which is version 1.2.49 instead of 1.2.50, which worked like a charm. Until 1.2.50 is out for Stretch, I recommend installing Wheezy's 1.2.49.

Thanks again for the help to everyone who replied and commented, you all are truly wonderful human beings!

  • I needed this to install the Unity Editor on Debian Stretch, the Wheezy 1.2.49 version worked. Thanks! Commented Apr 5, 2017 at 14:09
  • Can you tell me how you installed the wheezy package? I've never had to do this sort of thing before. Commented Jan 11, 2018 at 0:36

    I don't know what the exact version you need to install is, so that changes the output of the command, but you generally want to follow the instructions here: askubuntu.com/questions/428772/…, which will help you find the right version. Just look for the one that says wheezy where saucy/main is in that example link. Then just install it with: apt-get install libpng12-0=$VER. Paste apt-cache policy libpng12-0 output if you hit issues. Commented Jan 12, 2018 at 2:18

You can download the libpng12-0 from.

http://packages.ubuntu.com/xenial/i386/libpng12-0/download for 386 architecture

and

http://packages.ubuntu.com/xenial/amd64/libpng12-0/download for 64 bits.

    While I normally hate grabbing .deb's for other distros, I manually downloaded the 64 bit .deb for Ubuntu and receive the same error as described in the OP. Thanks for trying though! Commented Dec 21, 2016 at 15:11

It looks like there's something a bit messed up with libpng12-0; it installs its .so in /lib/x86_64-linux-gnu (on amd64), but also drops a link in /usr/lib/x86_64-linux-gnu — and I think that's what's breaking here.

On my system everything is installed correctly (libpng16-16 and libpng12-0), but I also have libpng-dev installed (version 1.6), and that allows the libpng12-0 link to be resolved. If my theory is correct, you should be able to do

apt-get install libpng-dev apt-get install libpng12-0

and have a working libpng12...

  • That was a really solid theory, because I didn't have libpng-dev installed. So, I have now installed it (1.6.26-6 is the exact version) and tried to rerun the install for libpng12-0, unfortunately, I received the same error =(. Any other ideas? Commented Dec 21, 2016 at 15:12
  • Unfortunately not, I've tried removing and reinstalling libpng12-0 on my own system and it works fine, with and without libpng-dev. Commented Dec 21, 2016 at 16:41
  • Thanks again for your help, but I figured it out. I'm running Stretch (testing), which doesn't have libpng12-0 out officially. I was trying to install Jessie's version (1.2.50). When I installed Wheezy's version (1.2.49), everything was fixed and it works like a charm. Appreciate your time though! Commented Dec 21, 2016 at 16:54
  • I know, libpng16-16 is only available in testing and unstable, so I figured you were running at least testing; and libpng12-0 isn't available there any more. I tested with the Jessie version too... But if the Wheezy version works, that's good. You should probably try to get rid of the need for libpng12-0 entirely though, it does have a few security holes!

You need to edit (as superuser) /etc/apt/sources.list and add a line deb http://ftp.de.debian.org/debian wheezy main then save this and enter next command sudo apt-get install libpng12-0 and your issue may be solved

    Good idea, but it doesn't work for me. Commented Mar 15, 2019 at 16:46

I was able to finally install this file into my kali build.

I had to download "libpng-1.2.49" the file that runs on debian 7 "wheezy" as a .tar.gz file.

extract it through the normal methods than using the readme was able to successfully install the file and get the desired result i was looking for.
