I have Ubuntu 16.04.1 multi-arch. I installed libjpeg62 via synaptic. 

% ldconfig -p | grep libjpeg
    libjpegxr.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjpegxr.so.0
    libjpeg.so.62 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjpeg.so.62
    libjpeg.so.9 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjpeg.so.9
    libjpeg.so.8 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjpeg.so.8
    libjpeg.so.8 (libc6) => /usr/lib/i386-linux-gnu/libjpeg.so.8
    libjpeg.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjpeg.so

Here libjpeg.so.62 is located at /user/lib/x86_64-linux-gnu which is in my LD_LIBRARY_PATH. However, typing locate libjpeg.so.62 does not return anything. Why?

Also, when I run teamviewer, it complains that it cannot find libjpeg.so.62 either.

Update: as @oranja points out, after a while locate libjpeg.so.62 works. But teamviewer still cannot detect it.

I don't have admin right i.e. sudo, but can run gksu with my user password. So my plan is to install all dependencies for teamviewer via synaptic, then run the .tar.gz portable version of teamviewer. Any thoughts are welcomed.

  • @cl-netbox : sorry I am not in sudo group. But for some reasons I can run gksu just fine. So i guess I can't install any package from command line. So far the only option I know is to run gksu synaptic then install necessary packages from it. Any comment would help. – Tu Bui Jan 27 '17 at 12:05
  • @cl-netbox : I can't do that because I don't have admin right. It says "Sorry, user xxxx is not allowed to execute '/bin/bash' as root on xxxx". – Tu Bui Jan 27 '17 at 12:28
  • @cl-netbox: it is a work PC so it is understandable that I don't have admin right. The IT guy told me to install whatever I need via gksu synaptic. – Tu Bui Jan 27 '17 at 12:39
  • yet I can install packages via gksu synaptic, the libjpeg62 above is an example. gksu accepts my user password, but not sudo. I guess the system admin somehow lets me use gksu, but not sudo. – Tu Bui Jan 27 '17 at 16:56
  • Then your IT guy has to install TeamViewer for you ... tell him to do it the way as being described here -> http://askubuntu.com/questions/676224/teamviewer-not-ready-check-your-connection/676266#676266 ! :) – cl-netbox Jan 27 '17 at 17:19

It takes some time. The index for locate is stored by default in: /var/lib/mlocate/mlocate.db

And it is updated periodically by the updatedb utility.

If your run updatedb and still locate doesn't find libjpeg.so.62, that's odd and worth checking the configuration.

As for TeamViewer, I suspect that the problem is that you installed the 32bit version of TeamViewer, which looks for 32bit version of its dependencies.

Check this support article: https://www.teamviewer.com/en/help/363-how-do-i-install-teamviewer-on-my-linux-distribution

And this question: Installed Teamviewer using a 64-bit system, but I get a dependency error

Edit:

For TeamViewer 12.0.71510, dpkg -I reports the following dependencies:

libc6 (>= 2.11), libgcc1, libasound2, libdbus-1-3, libexpat1, libfontconfig1, libfreetype6, libjpeg62, libsm6, libxdamage1, libxext6, libxfixes3, libxinerama1, libxrandr2, libxrender1, libxtst6, zlib1g

You can either do a bulk install of all these, or install only those that TeamViewer complains about, but either way, you need to add the :i386 specification. So for example: libc6 becomes libc6:i386 and libjpeg62 becomes libjpeg62:i386. (This is also explained in the answer I've linked above, but the dependency list is outdated there).

If you have to use synaptic, there's an "Architecture" filter that might help to find the i386 versions of those dependencies.

  • thank u (up voted for answering half of my question). Now locate libjpeg.so.62 works, but my teamviewer still cannot find it. Plz check my updated question. – Tu Bui Jan 27 '17 at 11:52
  • I still don't have enough rep to comment on your question, but regarding sudo shell access, how about gksu gnome-terminal? This should get you a root shell, I believe. – oranja Jan 28 '17 at 13:14
  • gksu gnome-terminal does nothing. It just asks for password, then return to normal shell. I guess synaptic is the only app that I am allowed to run with gksu (just test gksu gedit and it doesn't work either). Fine, I just install all dependencies with synaptic then. Thank you for pointing out the list of dependencies. I verify that all are installed except libjpeg62:i386 and libxtst6:i386. The teamviewer log file also complains it cannot find these libraries. Searching for these libraries on synaptic returns nothing. Looks like they completely disappear from Ubuntu16.04??? – Tu Bui Jan 30 '17 at 13:20
  • It should be there, at least according to the official package index: http://packages.ubuntu.com/xenial/libjpeg62 ; It is also possible to download it directly and then figure out how to install it: http://packages.ubuntu.com/xenial/i386/libjpeg62/download – oranja Jan 31 '17 at 07:18
