Mint 21 on 32Bit architecture??

[TokoloshiMedicine]

I tried to upgrade to Mint 21 on my 3D printing PC; But it won't boot on the 64Bit version??
I see my architecture is i386, it should be amd64 correct?
dpkg --print-architecture
i386

Is my PC capable of changing to 64Bit and how?

Hello, TokoloshiMedicine.

As your inxi output near the top of your message clearly states

Code: Select all

CPU:
  Topology: Quad Core model: Intel Core i5-3470 bits: 64 type: MCP

Of course, this machine is 64-bit capable.

Good luck trying the Mint 21 live system and installing Mint 21 on your 64-bit Quad Core machine.

Regards,
Karl

You can't upgrade. You have to fresh install.
In any case you'll be better off with 64bit.
