Unfortunately there is no easy way to reproduce without building a new core. I build a core snap with the "networkd-allow-networkd-to-start-in- early-boot.patch" included.
With that our tests fail all over the place, e.g.: https://s3.amazonaws.com/archive.travis-ci.org/jobs/224387435/log.txt - search for "dial tcp: lookup". I created an image with the problematic core (it is revision 1754) and ran the testsuite: With an image generated with core r1754: $ kvm -m 1500 -redir tcp:10022::22 ./ubuntu-core-16-amd64.img/pc.img -snapshot $ export SPREAD_EXTERNAL_ADDRESS=localhost:10022 $ ./tests/lib/external/prepare-ssh.sh localhost 10022 $ spread -v -reuse external:ubuntu-core-16-64 but on qemu it is fine. However when I try this on linode I get: ... error: cannot install "jq": Get https://search.apps.ubuntu.com/api/v1/snaps/details/jq?channel=stable&fields=anon_download_url%2Carchitecture%2Cchannel%2Cdownload_sha3_384%2Csummary%2Cdescription%2Cdeltas%2Cbinary_filesize%2Cdownload_url%2Cepoch%2Cicon_url%2Clast_updated%2Cpackage_name%2Cprices%2Cpublisher%2Cratings_average%2Crevision%2Cscreenshot_urls%2Csnap_id%2Csupport_url%2Ccontact%2Ctitle%2Ccontent%2Cversion%2Corigin%2Cdeveloper_id%2Cprivate%2Cconfinement: dial tcp: lookup search.apps.ubuntu.com on [::1]:53: read udp [::1]:54730->[::1]:53: read: connection refused ... 2017/04/21 20:54:24 Failed tasks: 6 - linode:ubuntu-core-16-64:tests/main/auto-aliases - linode:ubuntu-core-16-64:tests/main/searching - linode:ubuntu-core-16-64:tests/main/snap-connect - linode:ubuntu-core-16-64:tests/main/snap-download - linode:ubuntu-core-16-64:tests/main/ubuntu-core-classic - linode:ubuntu-core-16-64:tests/main/ubuntu-core-create-user 2017/04/21 20:54:24 Failed task prepare: 10 - linode:ubuntu-core-16-64:tests/main/auto-refresh - linode:ubuntu-core-16-64:tests/main/interfaces-content - linode:ubuntu-core-16-64:tests/main/interfaces-content-empty-content-attr - linode:ubuntu-core-16-64:tests/main/interfaces-fuse_support - linode:ubuntu-core-16-64:tests/main/interfaces-kernel-module-control - linode:ubuntu-core-16-64:tests/main/interfaces-snapd-control - linode:ubuntu-core-16-64:tests/main/refresh:strict_remote - linode:ubuntu-core-16-64:tests/main/revert-devmode:remote - linode:ubuntu-core-16-64:tests/main/revert:remote - linode:ubuntu-core-16-64:tests/main/snap-auto-mount 2017/04/21 20:54:24 Failed task restore: 1 - linode:ubuntu-core-16-64:tests/main/snap-auto-mount so ~10% of the tests on linode fail. Unfortunately I don't know yet why this is fine in qemu but not on linode. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1659195 Title: resolver regression on ubuntu-core from #1636912 Status in systemd package in Ubuntu: Confirmed Bug description: We had a bunch of test failures in our automatic tests for snapd since this ~Saturday (21.01.2017). All on core, all with errors like: """ error: cannot install "test-snapd-tools": Get https://search.apps.ubuntu.com/api/v1/snaps/details/test-snapd-tools?channel=stable&fields=anon_download_url%2Carchitecture%2Cchannel%2Cdownload_sha3_384%2Csummary%2Cdescription%2Cdeltas%2Cbinary_filesize%2Cdownload_url%2Cepoch%2Cicon_url%2Clast_updated%2Cpackage_name%2Cprices%2Cpublisher%2Cratings_average%2Crevision%2Cscreenshot_urls%2Csnap_id%2Csupport_url%2Ctitle%2Ccontent%2Cversion%2Corigin%2Cdeveloper_id%2Cprivate%2Cconfinement: dial tcp: lookup search.apps.ubuntu.com on [::1]:53: read udp [::1]:41766->[::1]:53: read: connection refused """ The key here is the: "dial tcp: lookup search.apps.ubuntu.com on [::1]:53: read udp [::1]:41766->[::1]:53: read: connection refused". It was random but in the ~150 integration tests we run for the core image we had about 5 of those everytime. Further debugging yielded that the /etc/resolv.conf is empty when the errors happen. It looks like the fix for https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1636912 is causing this behaviour for us. Reverting this change gave us stable tests again. I also tried to update to the latest resolvconf (the one that is reference in #1649931 and also in the followup bug #1649931). Using this resolvconf improved the situation dramatically. However we still got these errors from time to time with just updating resolvconf to the version in xenial-proposed. With the revert of #1649931 we have no prolbems so far in our test. If there is anything I can try in our image PPA to help with a fix I will be happy to do that.
