Hi James, [cc-ing submitter back, and youpi for the final comment]

Since that happens quite early, my first instinct was to look under the main-menu source package, which indeed contains some references to udpkg: kibi@tokyo:~/debian-installer/packages/main-menu$ git grep -i udpkg debian/changelog: - add "exec" to the udpkg calls, ash isn't able to optimize the fork debian/changelog: - Don't run udpkg --configure on virtual packages main-menu.c: /* Tell udpkg to shut up. */ main-menu.c: setenv("UDPKG_QUIET", "y", 1); main-menu.c: if (asprintf(&configcommand, "exec udpkg --configure --force-configure %s", p->p.package) == -1) If you want to read it online: https://salsa.debian.org/installer-team/main-menu/-/blob/master/main-menu.c#L835 main-menu is also the one getting the error according to Frédéric's syslog excerpt, so that would be somewhat consistent. I'm quoting it again before some comments: Apr 22 12:11:57 reopen-console: Looking at console hvc0 from /proc/consoles Apr 22 12:11:57 reopen-console: Adding hvc0 to possible consoles list Apr 22 12:11:57 reopen-console: hvc0 is preferred Apr 22 12:11:57 reopen-console: Adding tty0 to possible consoles list Apr 22 12:11:57 reopen-console: Adding inittab entry for hvc0 Apr 22 12:11:57 reopen-console: Adding inittab entry for tty0 Apr 22 12:11:57 reopen-console: Restarting init to start d-i on the console(s) we found Apr 22 12:11:57 init: reloading /etc/inittab Apr 22 12:11:57 init: starting pid 239, tty '/dev/tty4': '/usr/bin/tail -f /var/log/syslog' Apr 22 12:11:57 init: starting pid 240, tty '/dev/hvc0': '/sbin/debian-installer' Apr 22 12:11:57 init: starting pid 241, tty '/dev/tty0': '/sbin/debian-installer Apr 22 12:11:57 debconf: Setting debconf/language to en Apr 22 12:11:57 main-menu[272]: INFO: Falling back to the package description for brltty-udeb Apr 22 12:11:57 debconf: Setting debconf/language to en Apr 22 12:11:57 main-menu[272]: INFO: Menu item 'localechooser' selected Apr 22 12:11:57 main-menu[278]: INFO: Falling back to the package description for brltty-udeb Apr 22 12:11:57 main-menu[278]: INFO: Menu item 'localechooser' selected Apr 22 12:11:57 main-menu[278]: /var/lib/dpkg/status: No such file or directory Apr 22 12:11:57 main-menu[272]: /var/lib/dpkg/status: No such file or directory Apr 22 12:11:57 main-menu[272]: /var/lib/dpkg/status: No such file or directory Looking at that log, one sees two PIDs for main-menu (272 and 278), which could explain a very nice race condition: udpkg racing, one of them making the status file disappear from under the feet of the other one? See also two /sbin/debian-installer processes getting started beforehand (one on /dev/hvc0, one on /dev/tty). It looks to me this is a clear problem on the debian-installer side (how it deals with multiple consoles, similar to #940028 as you mentioned initially), rather than some possible issues with emulation?
