[ubuntu-mono] [Bug 1191195] Re: Cannot launch banshee: Unhandled Exception: System.DllNotFoundException: libgtk-x11-2.0.so.0

[Antonio19]

Well after posting the explanation of what I have done about libpng12
and libpng16 and reading from Chow Loong Jin (hyperair) that his
analysys of MONO points him to :

Mono: DllImport error loading library: '/usr/lib/libpng12.so.0: version
`PNG12_0' not found

I tried to remove the symbolic link I did add manually :

$ sudo rm /usr/lib/libpng12.so.0

The program looks at the first instance of the library found (may be).
So now it has to go at the right place to find it in /lib/x86_64-linux-
gnu

And it looks like now Banshee 2.4.1 is working fine :-). Then I just
performed an Ubuntu Update (Gnome) since I am a subscriber of the ppa
maintained by Chow Loong Jin (hyperair) and the last version 2.6.1 of
Banshee is now working in my system.

Thank you so much Mr. Chow Loong Jin (hyperair) for your time and
insight.

I will later try to compile and build a package on my system using the
libpng16 libraries.

Can you you please update the status of this bug to Fixed instead of
Invalid ? Thanks.

One day I hope Ubuntu will try to move on from libpng12 which is on old
version receiving only security updates. One day thre will be no support
at all for it.

Title:
  Cannot launch banshee: Unhandled Exception:
  System.DllNotFoundException: libgtk-x11-2.0.so.0

Status in “banshee” package in Ubuntu:
  Invalid

Bug description:
  I have the exact same problem as another bug already reported bug
  which has been marked as invalid.

  I strongly disagree with the term Invalid.

  When attempting to launch any version [even superseded ones] of
  banshee [for Precise 12.04 amd64] from the Command Line I get:

  $ banshee
  [...]
  [ERROR] FATAL UNHANDLED EXCEPTION: System.DllNotFoundException: libgtk-x11-2.0.so.0
  [...]
  [ERROR] FATAL UNHANDLED EXCEPTION: System.DllNotFoundException: libgtk-x11-2.0.so.0

  The reported missing library libgtk-x11-2.0.so.0 is part of package
  libgtk2.0-0 (I have as well libgtk2.0-0:i386 installed) and is located
  at the right place. i.e.

  $ locate libgtk-x11-2.0.so.0
  /usr/lib/i386-linux-gnu/libgtk-x11-2.0.so.0
  /usr/lib/i386-linux-gnu/libgtk-x11-2.0.so.0.2400.10
  /usr/lib/vmware/lib/libgtk-x11-2.0.so.0
  /usr/lib/vmware/lib/libgtk-x11-2.0.so.0/libgtk-x11-2.0.so.0
  /usr/lib/vmware-installer/2.1.0/lib/lib/libgtk-x11-2.0.so.0
  /usr/lib/vmware-installer/2.1.0/lib/lib/libgtk-x11-2.0.so.0/libgtk-x11-2.0.so.0
  /usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0
  /usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0.2400.10
  $ 

  The logs from strace and MONO_LOG_LEVEL are similar the earlier
  reported bug

  $ strace -e trace=open banshee 2>&1 | grep libgtk-x11-2.0.so.0\"

  $ MONO_LOG_LEVEL=debug banshee

  What is amazing in the MONO_LOG_LEVEL is the reporting of fictuous
  libraries not found i.e.

  /usr/lib/mono/4.0/mscorlib.dll.so: cannot open shared object file: No
  such file or directory

  Well have the .dll file (which is a Windows library extension type). I
  have never seen before a .dll.so (mixture of Windows and Linux library
  ?).

  Anyway I did have OpenGL installed and as well mesa (libgl1-mesa*
  packages).

  My Ubuntu 12.04 is properly functioning and obviously I have a lot of
  application installed. Of all the sound player installed only Banshee
  is unable to launch ...

  There is obviouly something wrong with this application.

  I am ready to provide further information upon request.

  In the mean time I will remove this application to avoid being annoyed
  by non functional updates from Ubuntu Updates required now a partial
  upgrade ...
