We became aware of this in the PR that started building trusty docker images: https://github.com/docker-library/official-images/pull/7029
For some reason, during the build process, the /etc/apt/preferences.d /ubuntu-esm-infra-trusty file got wiped, or was never created. This file pins the esm repository at a negative value, so that it won't be considered for upgrades unless esm is fully enabled. We are still troubleshooting that build process, and a PR was just created to reverse that change for now (see https://github.com/docker- library/official-images/pull/7038) A workaround is to create that pinning file manually: cat > /etc/apt/preferences.d/ubuntu-esm-infra-trusty <<EOF # Written by ubuntu-advantage-tools Package: * Pin: release o=UbuntuESM, n=trusty Pin-Priority: never EOF -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to ubuntu-advantage-tools in Ubuntu. https://bugs.launchpad.net/bugs/1854202 Title: Ubuntu 14.04 container fails to install app because of ESM dependency To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-advantage-tools/+bug/1854202/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
