I have a 32-bit server, running at 3.03 Ghz, 2gb RAM & 512 L2 Cache. Whenever I try to install Ubuntu 11.10 or 12.04, after installing the Base System, we get to Setting up Users and Passwords, then Configuring the package manager, which fails everytime. I've tried everything I can think of, but nothing seems to work. Any suggestions of what is wrong and how to fix it? Thanks.
Had the same problem with 12.04 LTS. My workaround was to wait for the disk partitioning phase, and then to open a console with Alt+F2.
What ISO image are you using? You should give that information, as that can be different even for same architecture. The x32 desktop version of the installer has a bug.
How does it fail?
Do you have internet connection working for the machine?
