I am following these steps to install FreeSurfer: https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall

When I run following commands:

    bert/surf/rh.white:edgecolor=blue \

I get this error:

freeview.bin: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory

And when I am trying to install this package:

sudo apt-get install libpng12.so.0

I am getting this error:

Reading package lists... Done

Reading state information... Done
E: Unable to locate package libpng12.0-0:i386
E: Couldn't find any package by glob 'libpng12.0-0'

I am totally new to Linux, please help!

  • Are you using Ubuntu 16.10? – fkraiem Mar 23 '17 at 3:38
  • Yes! I am using Ubuntu 16.10 – New_Coder Mar 23 '17 at 3:40

The software you are trying to run requires version 12 of libpng, which is no longer available in Ubuntu 16.10+. The best thing to do would be to install Ubuntu 16.04, or maybe let the developers of the software know about this problem so they can provide a version compatible with Ubuntu 16.10.

you can either

install the supplied .deb file available from



sudo dpkg -i libpng12-0_1.2.54-1ubuntu1.1_amd64.deb

or compile and install :

download source code https://packages.ubuntu.com/xenial/libpng12-0

wget http://archive.ubuntu.com/ubuntu/pool/main/libp/libpng/libpng_1.2.54.orig.tar.xz

tar xvf  libpng_1.2.54.orig.tar.xz 

cd libpng-1.2.54
make -j8 
sudo make install

then update the links with:

sudo ldconfig

prior to any of this assure you machine has these preliminary packages installed ... baseline for any dev kit

sudo apt-get update
sudo apt-get upgrade 
sudo apt-get install libtool autoconf build-essential pkg-config automake tcsh

good news is freesurfer 7 on Ubuntu 20.04 runs fine out of the box

    Also works in Ubuntu 18.06. – hailinzeng Oct 4 '18 at 5:38

I was having problems installing SAS on Ubuntu 18.04. Some instructions following will only apply to those installing SAS.

The first problem was that the installation would hang on hot fix W83001. Solution is to move hot fix W83001pt.zip out of the <depot>/hot_fix directory so it is not installed.

The second problem was that the following package was needed and not installed by default on Ubuntu: libjpeg.s0.62. Installation was done as follows:

sudo apt install libjpeg62

The third problem was the missing package discussed on this page, libpng12.so.0. It was downloaded from this link and installed as follows:

sudo apt install ./libpng12-0_1.2.54-1ubuntu1.1_amd64.deb

After this, I was able to run the SAS software. Thanks everyone for posting the tips.

Another alternative is to create symbolic links to both PNG and JPEG libraries

sudo ln -s -T /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib/x86_64-linux-gnu/libjpeg.so.62
sudo ln -s -T /usr/lib/x86_64-linux-gnu/libpng16.so /usr/lib/x86_64-linux-gnu/libpng12.so.0

It will generate some warnings (libpng warning: Application built with libpng-1.2.7 but running with 1.6.28) when running. However, Freeview works ok.

    I know it's not the same problem, but for anyone trying to install gmic on gimp (ubuntu 17.10) this trick doesn't work ./gmic_gimp_qt: /usr/lib/x86_64-linux-gnu/libpng12.so.0: version 'PNG12_0' not found (required by ./gmic_gimp_qt). The workaround of @Diogo Alves works though for gmic. – franzlorenzon Oct 27 '17 at 13:11

You can use:

wget http://mirrors.kernel.org/ubuntu/pool/main/libp/libpng/libpng12-0_1.2.54-1ubuntu1_amd64.deb
sudo dpkg -i libpng12.deb
