[ David Kalnischkies ] * apt-key: warn instead of fail on unreadable keyrings (LP: #1642386) * show apt-key warnings in apt update (Closes: 834973) [ Julian Andres Klode ] * test-releasefile-verification: installaptold: Clean up before run -- Julian Andres Klode <juli...@ubuntu.com> Wed, 23 Nov 2016 20:09:27 +0100 ** Changed in: apt (Ubuntu Xenial) Status: Triaged => In Progress ** Description changed: + [Impact] + Breaks update on systems with unreadable GPG keys + + [Test case] + Run apt update with an unreadable GPG key file in trusted.gpg.d. This should work and (stretch goal) print a warning about the key being unreadable. + + [Regression potential] + Low risk. We check that very situation in the automated test suite now like we did a lot of other situations before. The fix has been available in apt since 1.3_rc3 on Aug 30, and there have been no regressions reported since then. + + [Original bug report] Hello, a recent apt update appears to have broken apt entirely. A coworker reported seeing troubles: http://paste.ubuntu.com/23487135/ To test, I upgraded my laptop then immediately re-ran apt-get update && apt-get -u dist-upgrade: sarnold@hunt:~/Downloads$ sudo apt-get update && sudo apt-get -u dist-upgrade Hit:1 http://mirrors.kernel.org/ubuntu xenial InRelease -
