This has now been resolved by Bug 1844504, mentioned above by Mauricio. Since the patches to fix the pty issues are no longer needed, I will not SRU them.
Thanks for your help Christian and Mauricio. Successful build log of a new libvirt test package, dated today: https://launchpad.net/~mruffell/+archive/ubuntu/sf242822-test/+build/18001022/+files /buildlog_ubuntu-xenial- amd64.libvirt_1.3.1-1ubuntu10.28+sf242822v20191031b1_BUILDING.txt.gz ** Changed in: libvirt (Ubuntu Xenial) Status: New => Won't Fix -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial. Matching subscriptions: Ubuntu 16.04 Bugs https://bugs.launchpad.net/bugs/1843674 Title: FTBFS of libvirt in Xenial Status in libvirt package in Ubuntu: Fix Released Status in libvirt source package in Xenial: Won't Fix Bug description: [Impact] * libvirt became FTBFS in xenial due to other changes. Most likely a newer deboostrap that was used. * The fix just modifies the self-tests (not the active code that runs in an ubuntu users env) * The change is already active in Ubuntu in later releases via https://salsa.debian.org/libvirt-team/libvirt/commit/2be70b3 https://salsa.debian.org/libvirt-team/libvirt/commit/7baa0daf https://salsa.debian.org/libvirt-team/libvirt/commit/0ce5eb75 [Test Case] * Build libvirt in Xenial on LP infra and while doing so do not trigger test fails in test-openpty and test-posix_openpt [Regression Potential] * Since we only change self-test code that runs at build time the runtime should show now regressions. The one thing I can think of is that a rebuild could always change something (even a no change rebuild) but since we want to bundle it with other SRUs there would be a rebuild anyway - hence I'd think this has no regression risk of its own. [Other Info] * This should not be fixed standalone but bundled with some other SRU to avoid useless rebuilds - and even more so - users downloading updates for now gain. --- Due to a unknown other update libvirt became an FTBFS in Xenial. The issue shows up at build on launchpad infra and has two seld-tests broken. From the build log: FAIL: test-openpty ================== openpty returned -1 FAIL test-openpty (exit status: 1) FAIL: test-posix_openpt ======================= ../../../../gnulib/tests/test-posix_openpt.c:52: assertion '0 <= master' failed FAIL test-posix_openpt (exit status: 134) This is somewhat familiar to bug 1641615 but showing up again in Xenial now for yet unknown reasons. The later re-occurrence of this outside of Xenial was later on fixed by [1] for good. Probably now triggering by some SRu of a lib into Xenial (or unlikely some change in the builder setup). We want to add that to Xenial as well to have it build fine again.
