32 bit x86 setups are very rare now under Linux, and you are really on your own - people no longer test with them and some software no longer supports 32 bit (eg Docker; I gather it will go multi architecture soon but I doubt much stuff will be built or tested on 32 bit x86 anyway). As your hardware can run 64 bit you have no reason to run 32 bit.

I hope you can imagine why I might not want to reinstall the OS and have to redeploy half a dozen other things, just so this particular one gets easier.

Because you are managing your servers as pets not cattle? Because you did the installs manually and can't replicate them? Thats what you need to fix, with automated deployments that is a non issue.

So why wasn't that at least documented?
