Downgrading is no longer possible. No magic potion available. Move to unpacking a virtual environment created on U22.04 but python2 would still have to be installed but the script would be much less invasive.

Not a bug, just evolution with the newest OS.

Disappointing but good to know!

Patch has been applied, so that mainline IIAB installs on Ubuntu 24.04 can now proceed:

• PR Bypass KA Lite install during initial install of IIAB, on recent OS's like Ubuntu 24.04+ #3733

I'm tempted to leave this ticket open for a few weeks, just in case others have other opinions on how to proceed here?
