i might have stumbled across why this is happening. although i'm not sure if this was an expected side-effect.
to keep from running into kernel module issues and things of the like, the installers that i use [with a preseed that's dynamically generated per release, per machine] are sourced from dists/stable/main/installer-${arch}/current/images/netboot/debian-installer/${arch}/ , which i use to stand up VMs in xen [also specifying mirror/suite=${suite} as desired on the kernel cmdline]. with that change that was made in august [bug #758561], the stable debian-installer image still expects aptitude to be present in /target, but i'm guessing the dependency resolution doesn't bring it in [because it's no longer essential], so the install falls on its face in the stated way. the summary appears to be, due to the change made in august, stable install media can no longer be used to install testing or unstable. i'm unsure as to whether that was a supported configuration in the first place, but it helped me avoid other issues. i suppose i could force the preseeds to try to pre-install aptitude into /target, to work around the issue. or a decision might be made to have aptitude be marked as essential again, until jessie rolls into stable [and it might no longer be reasonable to expect such usage to work]. if it wasn't supposed to work this way in the first place, i apologize for raising it as an issue. david On Wed, 2014-11-12 at 17:08 +0100, Ansgar Burchardt wrote: > Default Identity <n...@photongenic.net> writes: > > in testing and unstable, debian-installer installations can no longer > > complete, because they hang at the "select and install" screen. this > > can be observed in /var/log/syslog: > > > > Sep 19 15:43:13 main-menu[4024]: INFO: Menu item 'pkgsel' selected > > Sep 19 15:43:15 pkgsel: checking for (security) updates to the base > > system > > Sep 19 15:43:16 in-target: Can't exec "aptitude": No such file or > > directory at /usr/bin/debconf-apt-progress line 130, <STDIN> line 2. > > Sep 19 15:43:16 in-target: Use of uninitialized value in vec > > at /usr/bin/debconf-apt-progress line 274, <STDIN> line 2. > > Sep 19 15:43:16 in-target: Use of uninitialized value in vec > > at /usr/bin/debconf-apt-progress line 275, <STDIN> line 2. > > Which version of the Debian Installer are you using? > > pkgsel no longer uses aptitude: > +--- > | Date: Sun, 02 Feb 2014 16:17:31 +0100 > | > | pkgsel (0.42) unstable; urgency=low > | * Drop last use of aptitude.
