Attached is a trivial patch [in retrospective] I just committed upstream which should fix this issue – I have only verified it by logchecking with the two status files from the buglog (again: thanks!) through, I haven't actually run it on a real system so testers welcome!
That should be easily backportable into 2011 (= the time this regression was introduced) even if the surrounding code changed a bit over time. Could potentially also be worked around with strategic duplication of Pre-Depends in Depends. So, what going on? apt doesn't check if Pre- Depends are satisfied before configuring but that is actually hard to trigger as apt does check them for unpack and the window between unpack and configure is usually very small as apt is actively trying to have it very small (compare immediate configuration) so all my attempts at constructing a testcase for it failed so far… ** Patch added: "0001-recheck-Pre-Depends-satisfaction-in-SmartConfigure.patch" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1560797/+attachment/4636054/+files/0001-recheck-Pre-Depends-satisfaction-in-SmartConfigure.patch -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1560797 Title: package systemd-sysv 225-1ubuntu9.1 failed to install/upgrade: libgcrypt20 was unconfigured during 15.10 to 16.04 upgrade Status in apt package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: Happened during upgrade to 16.04, don't know any more details.
