** Description changed: + [Impact] + + TODO Grant + + [Test Plan] + + Reproduce the bug on a container by adding an apt repo that doesn't have + an "Origin" speficied. When running apt update or apt upgrade you will + see "Segmentation fault (core dumped)" in the output. For example: + + ``` + lxc launch ubuntu-daily:bionic test-apt-hook-segfault + lxc exec test-apt-hook-segfault -- bash + # inside the container now + wget -qO - https://packages.irods.org/irods-signing-key.asc | sudo apt-key add - + echo "deb [arch=amd64] https://packages.irods.org/apt/ xenial main" | sudo tee /etc/apt/sources.list.d/renci-irods.list + apt update + apt install irods-dev=4.2.2 + apt update + ``` + + At the end of the output of the last apt update command, you will see + the segfault. + + To see the fix in action, install the new ua version from our staging PPA. Continuing on the same container: + ``` + add-apt-repository ppa:ua-client/staging + apt install ubuntu-advantage-tools + apt update + ``` + There should be no segfaults anymore. + + [Where problems could occur] + + TODO Grant + + [Other Info] + + TODO Grant + + [Original Description] + This bug has been brought to my attention by a UA Canonical customer. In this current situation, there is no attached UA subscription. - They can repeatly reproduce the error on a newly installed Bionic system + They can repeatly reproduce the error on a newly installed Bionic system Support (STS/SEG) can't reproduce it so far.
