Opera not installing correctly

[webguy]

Hey,

I have Ubuntu 5.10 and Opera will not install correctly. Below is the 
output I recieved today when I tried to install it with apt-get install.

sudo apt-get install opera
Reading package lists... Done
Building dependency tree... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  opera: Depends: libqt3c102-mt but it is not installable
E: Broken packages
robert at webguy:~$ sudo apt-get install libqt3c102-mt
Reading package lists... Done
Building dependency tree... Done
Package libqt3c102-mt is not available, but is referred to by another 
package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  libqt3-mt
E: Package libqt3c102-mt has no installation candidate

Here is my /etc/apt/sources.list file:
