So solution is to install 32 bit variant of the library Step 1: Find the package that includes this library #dpkg -S libgthread-2.0.so.0 libglib2.0-0:amd64: /usr/lib/x86_64-linux-gnu/libgthread-2.0.so.0 Step 2: Install 32 bit version of the same so add i386 instead of amd 64. I tried to download and install the.deb package from, but upon installation software center says already a new version is installed Any ideas how to resolved this.? Solution The problem was the IDA is looking for 32 bit libraries and what I had on my system was 64 bit libraries and what I downloaded was also 64 bit, that is why Software Center said it already exist. I installed 32 bit libraries and resolved them but i'm stuck with the libgthread-2.0.so.0. I was trying to try run IDA debugger on my Ubuntu 13.10 and many 'Error while loading shared libraries' showed up. I have Ubuntu 14.04 圆4 and I am running Ida pro V6.6 in. The IDA Disassembler and debugger is a multi-processor disassembler and debugger hosted on the Windows, Linux and Mac OS X Platforms.
