When I start synaptic, it throws the following:

$ sudo synaptic
[sudo] password for xxxxx: 
synaptic: error while loading shared libraries: libept.so.1.aptpkg4.12: cannot open shared object file: No such file or directory

What is the reason and what is its solution?

  • Hey Tabrez try gksudo synaptic. While I look into this. – mojo706 Sep 01 '13 at 10:06

    looks like you do not have libept installed. try installing it then report back – mojo706 Sep 01 '13 at 10:13
  • @mojo706, Thanks for replying and sorry that I disappeared as soon as I asked the question. Synaptic was just fine yesterday. And yes, libept is installed already. – Tabrez Ahmed Sep 01 '13 at 14:51
  • Where is it exactly? What's the output of locate libept.so.1.aptpkg4.12? – Alaa Ali Sep 01 '13 at 17:14
  • @Braiam You might want to post something like that as an answer. Tabrez Ahmed: Did you install any software since Synaptic last worked? (I'm especially thinking of software installed not through the package manager, but please tell us about any software.) Did you edit your ldconfig configuration, for example by adding anything inside /etc/ld.so.conf.d? – Eliah Kagan Sep 01 '13 at 17:15

You should reinstall libept1.4.2 since for some reason or other is not present in the /usr/lib directory. For doing so:

sudo apt-get --reinstall install libept1.4.12

You may check if it exist or not doing:

$ ls -l /usr/lib/libept.so.1.aptpkg4.12
-rw-r--r--. 1 root root 596740 jun 21  2012 /usr/lib/libept.so.1.aptpkg4.12

I've got an equivalent error message for using synaptic with libept1.4.16. The problem is that the necessary library libept.so.1.aptpkg4.16 doesn't exist, but libept.so.1.aptpkg5.0 can be found in /usr/lib/x86_64-linux-gnu/ instead of that. Indeed libept1.4.16_1.0.14+b2_amd64.deb seems to be faulty. It claims to be libept1.4.16, but in reality it installs libept1.5.0 instead of this. To solve the problem I just copied libept.so.1.aptpkg4.16 from the older version libept1.4.16_1.0.14+b1_amd64.deb to /usr/lib/x86_64-linux-gnu/ and used ldconfig -v afterwards. Now synaptic starts again.
