> you will not be able to transfer your hard-drive/SSD to an older machine that does not support x86-64-v3. Usually, we try to ensure that moving drives between systems like this would work. For 26.04 LTS, we’ll be working on making this experience cleaner, and hopefully provide a method of recovering a system that is in this state.

Does anyone know what the plans are to accomplish this?

If I were them I would make sure the V3 instructions are not used until late in the boot process, and some apt command that makes sure all installed programs are in the right subarchitecture for the running system, reinstalling as necessary.

But that does not sound like a simple for non technical users solution.

Anyway, non technical users using an installation on another lower computer? That sounds weird.

I am probably going to be the one implementing this and I don't know what I am going to do yet! At the very least we need the failure mode to be better (currently you get an OOPS when the init from the initrd dies due to an illegal instruction exception)
