Yes, this is a known issue. This is because Bookworm only supports 32-bit CPUs that are fully Intel compatible. You will find that there are other binaries such as ffmpeg that fail with the same problem. (This is from memory. I have a similar system that is "almost" Intel compatible, but cannot run Bookworm due to these issues.)
The fact that these processors are still sold today is interesting, though. A big part of the argument for limiting 32-bit support has to do with the assumption that they are all "very old" systems. So a NEW 32-bit processor might change that discussion. This is perhaps a better link for that, though, since it shows a product based on that CPU, rather than just a discussion about it: https://icop.com.tw/product/VDX3-PITX#! (Note: The site uses a self-signed certificate. Bleh.) It doesn't list a price or availability, though, which suggests that it may NOT actually be sold any more. Do you have an example of a site where these are available for purchase as new (not used or refurbished)? --J > On Jun 8, 2024, at 02:25, Laszlo Merenyi <meren...@protonmail.com> wrote: > > Message-id: <e1qt2rj-00000000pnx-3...@drop.zugschlus.de> > In-reply-to: <529d4728-d26f-43ff-a957-54b29652d...@neoquasar.org> > References: <529d4728-d26f-43ff-a957-54b29652d...@neoquasar.org> > > Hello, > I encountered a similar sudo issue with Bookworm installed on a Vortex86DX3 > CPU based embedded computer. > Vortex86 series chips are less known x86 CPUs, that are manufactured and are > available on-the-market still today.
