I'm trying to run a game (PRIME, an old Rougelike found here) and after downloading the 64 bit linux version, and going to run it, I get this error response:

./prime: error while loading shared libraries: libsigsegv.so.2: cannot
open shared object file: No such file or directory

Now, I've checked that I've got that file in my library, and it's up to date. The last time I asked this question I was able to solve it simply with a sudo-apt-update, sudo-apt-upgrade. That isn't working this time.

(The italicized note above is technically a mistake. I did have that file, but not the i386 version. Take a look at the accepted answer and my comments to see how we discovered that!)

My real item is this, though: Shared library problems are a pretty common error, it seems, and although the library in question changes, the other common issue is that the library exists, but for some reason the executable (or the user?) can't find it?

This is also not the first time I've had this issue on this system.

Is there a general solution or approach to shared library problems?

I came across this using ldconfig but I haven't been able to get it to work.
