Bug#1026027: graphical installer: using nano in a installer shell fails

And the packages which ships it (libvte-common) did not receive any updates since buster. So there's no change there I guess. And on the other side: on debian-11 installer, TERM is also set to 'xterm' as it is now on the dailies, so also no changing here. But in debian-11 it works nevertheless! Hmm. Kibi mentioned that this bug comes from ncurses (however I fail to see any details here), should this be redirected to ncurses then?

Oh, so it is. Hmm, I seem not to have checked that bit, sorry. Perhaps the presence of the termcap file is irrelevant, or could it be that nano used to be able to make use of that, and more recently only supports terminfo? > Hmm. Kibi mentioned that this bug comes from ncurses (however I fail to > see any details here), should this be redirected to ncurses then? Well, ncurses-base provides /lib/terminfo/x/xterm (in normal .deb packages), so perhaps that's why, although AFAICS it wasn't including that file in the udeb, even when things were working. Making it ship a terminfo for xterm in the udeb would probably fix things, but I think it would also be quite nice to know why it broke.

Re: Compatibility between kernel and modules

One thing to note here is Debian Installer netboot images. Those built with a certain kernel-image-$ABI-di can download *-modules-$ABI-di udebs for that ABI at installation-time, but don't check the actual version. They do display an error if the archive doesn't have modules for that ABI name. I recently encountered this incompatibility with a slightly out-of-date custom netboot image I was testing, and it's not really visible to a user that this has happened. It complained about kernel not supporting RAID and so on, then inexplicably failed after partitioning (looked like it couldn't mount root as ext4). I needed to build a new image. > We need to fix that somehow. Options are as far as I see > - remove BTF from modules, > - allow to load modules even on BTF mismatch, or > - reinforce that a user can't do that. I fear I'm being ignorant here, but 'Bump ABI on every build' sounds to me like it would be technically valid. Although, that might defeat the purpose of tracking ABIs, is that the reason it's not an option? > If we go with the last option we would have also some direct advantages. > We could stop signing modules with the secure boot key, but use a > temporary key. This would for a system with signature checking enabled > effectively trash all possibilities to load modules for a different > kernel build. Anyway, I guess it would be possible to modify d-i to check modules more strictly, by using package version instead of ABI name (in src:anna ?).
