Here's the error message I got:
I had to try to install 32-bit libraries several ways before it worked. Just typing sudo apt-get install ia32-libs or that with more text after it didn't work. The terms and conditions are so big that they erased my Terminal log.Error running /home/radomir/TimeTrex/postgresql/bin/initdb -U postgres -E 'UTF-8' --locale='en_US.UTF-8' -D /home/radomir/TimeTrex/postgresql/data/ : /home/radomir/TimeTrex/postgresql/bin/initdb.bin: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory
I tried searching for this, and it seems I need to keep installing more 32-bit libraries.
