I also have to pass -vga vmware to qemu, so the linux console stays in pure text mode, no fbcon. As I was guessing, it's the console-setup configuration that mangles everything, we'll be able to have a look. I couldn't reproduce it with all other parameters being the default, I'll dig more.

Bug#1065570: Interface border is replaced by ascii chars
Sorry, I don't mean to make you chase information. The only other difference is our pxelinux.cfg. We are using a minimal pxelinux in order to bypass the interactive menus with the following content. default linux label linux kernel debian-installer/amd64/linux append initrd=debian-installer/amd64/initrd.gz ip=dhcp auto=enable language=en country=US locale=en_US.UTF-8 keymap=ansi hostname=debian domain="" url=tftp://10.0.0.1/preseed.cfg I attempted a minimal repro using a command similar to yours but using "qemu-system-x86_64 -enable-kvm" (because I can't seem to find the package that has the kvm bin) and did not get the bug. I know it's not isolated to VirtualBox because I have video of the bug happening on a bare metal install (https://youtu.be/-OiJVJp8SxQ bug occurs at about 1:05). After some digging, I saw that the original netboot.tar.gz had pxelinux.cfg symlinked to debian-installer/amd64/pxelinux.cfg which has a default file symlinked to ../boot-screens/syslinux.cfg (realpath debian-installer/amd64/boot-screens/syslinux.cfg). The QEMU reproduction I tried I edited that file directly, whereas the other tests I've done a script has replaced it pxelinux.cfg/default with a new file (removing the symlink entirely). I modified our script-generated tftp directory (for VirtualBox) to fix the symlink (putting the above contents into the debian-installer/amd64/boot-screens/syslinux.cfg file directly) and that didn't fix the issue (I thought I was onto something). I reset the TFTP dir to just the preseed.cfg (so not our pxelinux.cfg) and input the kernel parameters in the default menu. One thing I noticed was the default parameters include VGA=788 (which our menu above was missing). This appears to have fixed the issue. I ran the QEMU test mentioned earlier using the pxelinux.cfg above, but qualitatively it looked like it was running in a different graphical mode. With this information, I think this may be related to the absence of the "VGA=" parameter in our boot parameters. I see there's an existing bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=969944 regarding the same parameter, but I don't see enough information there to say it's the same issue. That's all the relevant information I can think of for now. Maybe see if your KVM is able to reproduce using the pxelinux.cfg above or removing the "VGA=788" parameter from the kernel command line?

The mangling does not happen immediately. It happens after the "Installing the base system" step (not sure what the step after that is supposed to be).

I still cannot reproduce with unpacking the tarball and running kvm -net nic -net user,tftp=$PWD,bootfile=pxelinux.0 -drive -m 1G and passing the kernel parameters. Does the mangling happen right from the first screen, or after some steps? It could be useful to share your preseed.cfg (take care of removing any hardcoded password). Samuel

The machine is PXE booted with the kernel parameters: initrd=debian-installer/amd64/initrd.gz ip=dhcp auto=enable language=en country=US locale=en_US.UTF-8 keymap=ansi hostname=debian domain="" url=tftp://10.0.0.1/preseed.cfg Console is accessed over VGA. VMSVGA for the VirtualBox tests we've ran and a VGA KVM for the tests on bare metal.

Package: debian-installer Version: 20230607+deb12u5 I've been working with a small team at my college trying to develop a tool to automate PXE booting and installation. We have targeted Debian as the first OS we want to get working over PXE boot. On every test we've ran of the Debian installation process, there's a visual bug that occurs late in the installation process. Effectively, the border of the progress interface turns into Çâö repeatedly. You can see an image of it in the issue here https://github.com/xeluior/genisys/issues/82 This happens every install. We have tested it on a small selection of hardware (I don't have the details on hand right now) and in virtual machines (VirtualBox). The debian-installer version is the one bundled with https://deb.debian.org/debian/dists/bookworm/main/installer-amd64/current/images/netboot/netboot.tar.gz I'm not sure where to start looking for this so let me know what other information would be useful. Thank you, Robert Gingras
