[Touch-packages] [Bug 1974456] Re: regression: apt.postint fails if never previously configured
juliank - No. Our "overly complex" build must support environments without direct access to the ubuntu servers. Therefore we download all needed Ubuntu packages as a front-end step, putting them in an IBM- internal archive. At build time, reprepro is used to put them in to a local filesystem repo which then feeds debootstrap. The front-end step certainly downloads from focal-updates, always using apt-get download. -- 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/1974456 Title: regression: apt.postint fails if never previously configured Status in apt package in Ubuntu: Confirmed Status in apt source package in Bionic: Confirmed Status in apt source package in Focal: Fix Committed Bug description: [Impact] bootstrapping a system with apt that fixes #1968154 fails in focal and bionic, as they try to execute the config file that is being removed.

[Touch-packages] [Bug 1974456] Re: regression: apt.postint fails if never previously configured
The IBM Secure Service Container (SSC) environment uses Ubuntu 20.04 for zLinux. During our periodic package refresh, apt 2.0.8 caused this failure in the debootstrap step of our build process: Setting up apt (2.0.8) ... /var/lib/dpkg/info/apt.postinst: 65: /etc/kernel/postinst.d/apt-auto-removal: not found dpkg: error processing package apt (--configure): installed apt package post-installation script subprocess returned error exit status 127 (as reported here). We backed off to apt 2.0.6 for current sprint/release and joined this bug.
